Ebrahim AharpourJava/ Hippo Developer
My name is Ebrahim and I’m an experienced Java developer with a thrust for learning and a passion for latest technology. I’m a firm believer of open source and have a long history of contributing to the open source community. I believe in the virtue of knowledge sharing and strive to create an atmosphere where people are passionate about technology and share their ideas, visions and aspiration.
My name is Joost and I am a Hippo developer at Open Web. I'm a positive person and I love to contribute in getting positivity out everything. That’s why it was an easy choice to join Open Web. In addition to it being a logical step in my career, my colleagues are perfect consulting partners concerning innovations and personal interests. Moreover, I can make a good contribute to the growth of the company.
I am interested in the spiritual side of life and am involved with Reiki. This also helps me in my work. The hippo CMS has little secrets for me, as I have witnessed Hippo 7’s birth and have been constantly involved with Hippo projects ever since.
I do not give up very easily; I am effective in finding problem causes in order to find the best way to solve them. This helps me debugging code but also with other elements of a project, where I keep a balance between priority, profit and costs.
Gridi SerboHippo Developer
My name is Gridi and I am employee "001" of Open Web. I am a Java software developer that has fallen in love with Hippo CMS since the first day.
After few years of great co-working experience with the founders of this company, I had no doubts about the success of the new adventure and joined Open Web immediately after its foundation.
When I am not playing with Hippo, I cultivate my two main passions, opera music and books on history. I also like playing strategy games and this has put me in optimization mode for every task I carry out, functionality I implement or problem I solve.
Matthijs TolkampJava/ Hippo Developer
My name is Matthijs and I’m a Java software developer who has extensive experience with implementations of Hippo. I have been a valuable team player at every project I have done caused my pragmatic way of working. Starting at Open Web was an easy choice for me because it's an environment where I can learn a lot from my fellow colleagues and also have the opportunity to build a really small company from the ground up. Being able to share knowledge between such a close group of coworkers has been the main reason for me to start at Open Web.
I love puzzles of any kind and trying to find a clever way to solve them. This is reflected in how I write Javacode, but also in my personal life where I love to play any kind of game. When I am not busy trying to demolish other people with board games, I act on stage with my own theater company or I read fantasy novels.
Wouter SpaakFront-end Developer
My name is Wouter and I work as a front-end developer. I like it when things are beautiful and work flawless and intuitively. As front-end developer at Open Web, I feel like I’ve done my job well when a user utilizes the software with a smile. At Open Web, I have the possibility to work with my colleagues on complex systems. Working together to find solutions that work and feel perfect, is something I find very challenging.
In my free time, I like cooking for friends and enjoying good wine with them. I also like to read literature and you'll find me visiting museums and galleries.
My name is Levente and I am one of Open Web’s founders. After almost 20 years of being involved with information technology, I still think that the more new things I know of, the more I realize what I don’t know yet.
I like to set goals and try my utmost to reach these. Starting my own business has been om my to-do list for too long. With my technical background, I think in terms of solutions rather than problems.
As a father of four very sweet girls, I try to find the balance between my company and my family. During running, I try to find the limits of my body. And if I have more free time, it happens too little, I also like to play the drums.
Cees HuismanService Manager & Marketing
I'm an enthusiastic and optimistic person without a 9-to-5 mentality. An experienced networker with cultural 'roots' and a healthy, wide scope on life and business. Quickly seeing opportunities, topics for contact and I can build and maintain relationships well. Diplomatic, honest, (inter)national professional sales experience and marketing are keywords that fit me well. To me Open Web feels like an honest bunch of professionals / friends who are ready for each other and for our customer. We want to be the best in order shape our big future plans even better.
In my spare time I like to visit in museums, I like to cook and play squash and golf. In addition, everything about classic sports cars, well brewed espresso and British tweeds will receive my undivided attention.
Jon KoopsFront-end Developer
I'm Jon and I'm front-end developer. I am keen on developing fast and intuitive web applications. My greatest reward is finding the right solution to a technical problem. Open Web offers me all options to work on a variety of technical challenges.
I spend my spare time reading about technical stuff using blogposts and books. Next I'm a huge science-fiction fan (🖖) and a more that enthoustic gamer.
Rob HaringJava/ Hippo Developer
I’m Rob and I’m an experienced Java/Hippo developer. My knowledge has been successfully applied amongst a large quantity of clients, mainly present in educational and publishing environments. I prefer to be part of a scrum-team to join forces with clients in the quest for not only to design the best possible application but also to build them. My motto is always: "Keep it simple, stupid". Only when the client is satisfied, I’m satisfied. And… laughter is essential during working hours (and beyond). Open Web offers me the right opportunities to work for and with interesting clients and to develop my professional skills.
In my spare time I love listening to good music and reading literature. With my family I visit museums and we go outdoors.
Ivor BoersJava/ Hippo Developer
Java is my passion. I’m specialised in developing and creating pragmatic solutions for complex programming issues. I work as a Java developer since 2006, mainly focussed on complex applications for the Bloomreach Enterprise platform. I’m adding value to this open source platform sharing eigen plug-ins, blogs and presentations; also at the annual Connect meetings. Working at Open Web offers me many opportunities to share my knowledge at large enterprises and interesting projects. The internal monthly knowledge sharing sessions are very valuable and help to keep my knowledge up-to-date. In my spare time I love to discover the world with my children and to play volleyball.
Ilja MuraskoHippo Developer
Hi, I’m Ilja and I have extensive knowledge of Hippo CMS implementations. Thanks to its open source nature and ability to be intergrated Hippo CMS is the perfect tool for complex ‘enterprise level’ solutions. I forsee a huge future with Hippo ahead; technical challenges are being tackled with joy as Open Web offers me a very motivating environment which supports learning and developing new skills.
About myself: I believe that daily physical excercise is essential to the right balance in life. Therefor I preform in triatlons and practice capoeira as my favorite sport. Do you like to read books? So do I!
Samer Al-WaealyField Manager/ Recruiter
I’m Samer and work as Field Manager/ Recruiter at Open Web and partially resonsible for new business and team expansion. Dedication and passion are my drives, while the choice for Open Web was easy: erxpertise, vision, appriciation, freedom and –without doubt- the team spirit. In my spare time I spend my energy in dancing, travelling. Actually I would love to do that more often, but lack of time is my enemy.
Dennis MuijsFront-end Developer
My name is Dennis, front-ender at Open Web. I'm love dealing with the visual aspect of applications, I can’t think of anything more beautiful than offering the perfect user experience with a well thought-out design. With the diverse set of customers and projects that offer Open Web, this is a perfect place for me to use my skills.
Outside Open Web I you will find in the garage where I work on my classic Mini. Otherwise, I'm into fitness or gaming.
Muhammed SenussiJava Developer
I am a Java developer, have experience in developing front-end and back-end systems and I’m aware of the latest Java and web technologies. My main interest are the topics like Big Data and the semantic web. My degree of learning endures beyond the professional field of work. Thus I am a passionate diver and I have very different hobbies like Muay Thai, astronomy, Mandala design and making music. At Open Web I’m offered a professional work environment with a very friendly character and am happy to be part of the Open Web family.
Rolf SmitAndroid Developer
I’m Rolf and have a passion for native mobile development with the specialty of the Android platform. Being an Android user of the start, I started writing my first apps just after the release of the rather stubborn Android 2.0 so Android has no secrets for me. My own apps, which are still used by thousands of users every day, are proof of that. I have an obsession for resolving bugs the right way and hate work-a-rounds or concessions. Performance and security are two requirements that I can not do without; UX is at least as important. Open Web gives me the opportunity to work on various challenging projects, in which I can use knowledge to achieve the best solution.
In my spare time, I'm really the guy with many hobbies, from working on cars, enjoying fish tanks to scuba diving.
Gerard KlijsJava/ Hippo Developer
I'm Gerard and work at Open Web as a Hippo / Java developer. I have experience with several major Hippo projects and with Apache Kafka. Recently, I have been working with Clojure and Clojurescript as a hobby project. As a company Open Web ticked all of my boxes for the fact that it's a small but fast-growing company with a very well setup for employees.
Kim SpiritusHippo/ Java Developer
My name is Kim. I'm a Java developer who came into contact with Hippo a few years ago and was immediately charmed by this CMS.
I like to dedicate myself to JDuchess, a Java user group for and by women in Java with the aim of getting more women involved in the Java community. I also enjoy teaching children how to program. My family is my most important leisure activity, but besides that I also like to run and I'm part of a cooking club.
I have chosen Open Web as an employer because it's a company with enthusiastic, dedicated and experienced employees who like to share their knowledge.
Jeroen van GoghManager Sales
As of February 1, 2018 I'm working at Open Web as Manager Sales, responsible for the commercial strategy of our organization and the existing and new clients of Open Web. After a career in the educational field, I made the switch to IT; I've worked for 11 years as an account manager and business developer for various organizations.
Every organization has its ambitions. It is important that the client receives the correct translation of these ambitions. Working together and sharing knowledge is key to my way of working. Finding solutions and offering solutions in consultation with the customer is the challenge that makes work fun. With this approach, a connection is immediately made between the client and Open Web.
In my spare time I'm often engaged in family business, but I also enjoy doing sports, including survival runs and running. Furthermore, I can enjoy a good book with a nice sun.
Edwin BenneheijJava/ Hippo Developer
Developing a good (web) application is a true team achievement. It is great to create a product together with and for the clinet, of which the end-user ultimately indicates that it works so well and so naturally. I've also been able to contribute as a Java / Hippo developer which offers a lot satisfaction.
During a Bloomreach / Hippo meeting I came in contact with Open Web; a fast growing company, informal and with a lot of Hippo expertise and mutual knowledge sharing as one of the pillars. That appealed to me very much.
I'm very fond of my work, but it's my family first for me. With my partner I have three (almost) teenagers and as soon as they come home with friends, our house is full of fun. Fortunately there is still an opportunity to read a book or to go outdoor to run a few miles or meet up with friends to contemplate life with humour.
Arno DiederikJava Developer
My name is Arno Diederik and I'm an experienced Java Developer. I like working in a team on both web applications and integration issues. My goal here is always to come up with solutions that are as simple and elegant as possible, to get feedback from the customer as quickly as possible.
At Open Web we have a lot of knowledge sessions, so that I can learn from other techniques and colleagues can use my expertise. In addition, Open Web offers me the opportunity to work on interesting projects, so I can develop myself further.
In my spare time I'm active in the 'korfball' sport. I'm a referee and coached referees to make them better.
Suganya VenkatasamyJava Developer
My name is Suganya Devi. I'm a Java developer as well as scrum master. I am good in converting the functional requirements into technical user stories. I believe the right approach to get the best application is to choose the right technology that fits the requirements.
I am looking for trust and respect from the client which will give me more confidence and commitment in delivering the work. My hobbies are spending time with my kids. I'm keen to learn and explore new digital technologies. Open Web provides me opportunities to explore and to be an expert by having high skilled technical people which helps me share the knowledge to move in my career level.

David KijkuitJava Developer
At age seven, I received a C64 from my parents and this immediately determined my career path. I was quickly interested in writing software myself. In the end, I was able to turn my hobby into work with passion as a Java developer. I think it's important to let customers participate into the development process and occasionally step out of the role as a developer. IT is always in motion and therefore there is always something to learn. At Open Web I find challenging projects, professional colleagues and the opportunity to broaden my knowledge.
When I am not working, I try to spend as much time as possible with my family. I also love motorcycling, gaming, robotics / IoT and building Android apps.
Vedran MoricJava Developer
Hi, my name is Vedran and I'm a Java Developer with focus on Spring framework, am enthusiastic about building software, positive attitude and easy to work with. At OpenWeb I get the opportunity to extend my skill set and develop on both personal and professional levels.
In my spare time I mostly reed about software development and related subjects.
Chirojyoti RavaFront-end Developer

Michel DrentheJava/ Hippo Developer
Hi, my name is Michel and I'm an experienced Java/ Hippo developer. I get a lot of energy from complex issues which I know how to solve using contemporary programming techniques. I also like to contemplate about the operative part in which software ends up and use that knowledge into real life.
Open Web actively participates in knowledge sharing through the monthly knowledge sessions. These sessions keep my knowledge up to date and in return I share my knowledge with my colleagues on various topics.
In my spare time I like to read about different programming techniques and I can appreciate a game.
My name is Gijs and I'm an experienced Java developer since 2000. I have carried out projects at various companies in various sectors, including financial institutions, energy & utilities and government.
In addition, I carried out backend, frontend and devops tasks within different team compositions. During assignments at clients, I like to work in a team in order to work together on new functionality, to identify and / or resolve issues.
With Open Web, input is valued, knowledge development and knowledge sharing are stimulated. There are regular knowledge sessions and colleagues are open to awnser questions and interesting technical discussions.
For me, Open Web is an employer with short management lines and also considers open communication and mutual appreciation of colleagues to be of paramount importance.
In my spare time, I am practicing a lot (fitness, cycling and running) and I enjoy dancing or parties where salsa or bachata shines music through the speakers.
VincentDigital & UX Strategist
Hi, my name is Vincent and I'm working as a digital and user experience strategist at Open Web. I have great passion for human behavior, conceptual thinking and creating digital added value for people. I believe in human centered creation by collaboration.
I really like short lines of communication, professionalism, a place where the employee comes first and innovation is in the DNA; the exact reasons I chose to work for at Open Web.
In my spare time I enjoy running, yoga and pilates. I'm also a running instructor, give clinics and bootcamps for everyone who wants to enjoy active movement more.
DaveSenior Java Developer
My name is Dave, I join Open Web as Senior Java Developer, but I hope I can use other backend languages like Kotlin. I chose Open Web because I believe in the ambitions of the company. Open Web wants to be more than a simple secondment. They do this for example with their internal projects and contributions to the open source community.
I like working with a company that wants to be actively involved and wants to share knowledge. I hope that I can professionally grow here and help the company achieve its ambitions. In my spare time I play football, board games and pub quizzes.
Starting February first, I will focus on growth of our organisation with great passion and pleasure within Open Web IT (together with Samer). From my collaboration with Open Web IT in 2018 it has become clear to me that we share the same vision and passion.
The common desire to grow in business and personal areas in which you really look at everyone's personal ambitions and act accordingly, is what has made me decide to make this transition.
AngeloFront-end developer/ UX designer
My name is Angelo Vreeswijk, I am 26 years old and I come from Koudekerk aan den Rijn. For this I worked in Amsterdam at Us Media, where I enjoyed working on various design and front-end projects. I want to further deepen the knowledge I gained there and use it at Open Web.
At Open Web I work as Front-End developer and UX Designer. With this combination I hope to be able to continue Open Web on a visual level and to be able to put down a clear brand identity. Together with Vincent I will put the UX discipline on the map. The reason I chose Open Web is because I am ready for the next step in my career and because I want to start a new fresh look at different projects. In addition, the Open Web team is a lot bigger than I was used to and I hope to learn a lot from the other Front-end developers.
In my free time I like to travel, preferably the whole world. And because my biggest hobby is cooking, I often invite family and friends for a nice snack and a drink.
RichardFront-end/ Angular developer
With a passion for development, I started as a junior developer, in the secondment. Where my start was mainly focused on Java development, I quickly started to focus on the front-end. In recent years I have mainly focused on Angular and the design and architecture of Angular applications, but also the design of test automation for this.
In addition to my work, I am particularly interested in 3D modelling and related issues such as game design, virtual/ augmented reality and 3D printing. I also like to read, you can find me behind the lens of a camera or I am (re) building something.
Kristel HoonhoudMarketing & Communication
I'm Kristel Hoonhoud and Marketing Communications Manager at Open Web from February 1. At my former employer Open Web was mentioned more than once, so they was not unknown to me. When I heard that Open Web was looking for a Marketing Communications Manager, that was music to my ears. After a couple of talks I was certain: I want to help Open Web to realise the ambitions, and here I am! Ready to make something beautiful out of it :)
Besides work, I also have plenty of other things that I like to do. Traveling, playing tennis, shopping, eating and having a drink with my friend, family and friends, that makes me very happy.
Arthur SchenkSenior Mobile Developer
I'm Arthur and I started as a Senior Mobile Developer at Open Web. I live with my girlfriend Carolien and my 2 daughters, Rosanne and Isabelle, in Bilthoven. Before I joined Open Web, I worked at Clay Solutions in Amsterdam as Mobile Developer on an IoT locking platform.

Nick van den BergFront-end Developer
My name is Nick, I started creating websites for real estate agents and then switched to single page applications and frameworks, where Angular appealed to me the most. Experience shows that I'm performing best in flat organisations. I'm working at Open Web as Front-end Developer and hope to make life for end users easier by delivering a smooth working application. Open Web appealed to me because it's commitment to employees, the opportunity to learn and actively sharing knowledge.
In my spare time I like to ride my motorbike, try to escape from an escape room with friends or spend time with my family.
Open Web is an honest team of highly skilled creative developers - I'm chuffed to bits working with these professionals.Cees, Marketing Manager
