My passion for IT began at a young age with the Commodore 64. Although initially limited to computer games, it sparked my curiosity about technology, from analog modems and the Tulip AT 386 PC, to the internet and handheld devices.
After completing my studies at Erasmus University Rotterdam, with a specialization in information management, I began my career in IT consultancy. In 2012, I joined QDelft, which was later acquired by Netcompany in 2019. Through establishing contracts, hiring the right employees, and implementing large IT projects, we built a successful company founded on long-term relationships with our clients.
Aside from work and family, sports are my greatest passion. Over the years, I&#8217;ve completed numerous half and full marathons, (ultra) trails, cycling tours, and triathlons. I have qualified for the 2024 Ironman World Championships in Hawaii, the birthplace of triathlon.
I see significant similarities between my approach to sports and work: goal oriented, collaborative with a skilled team, and a substantial amount of discipline and perseverance. The journey and relationships formed along the way are as crucial as achieving the goal.
With pleasure, I bring these qualities to the DNA of Respellion: be the best version of yourself!

People officer | Agile coach

At Respellion, I feel like a true responsible rebel. On one hand, I can employ my skills as an agile coach and scrum master, and on the other hand, I can contribute to building a modern organizational structure where trust and collaboration are prioritized.
As an agile coach, I work with both traditional and modern management techniques and competencies. I pay attention to the essence of various frameworks but without being dogmatic.
My strength lies in facilitating, guiding, and coaching individuals and teams. I believe that sincere attention to people provides a solid foundation of trust, that allows them to take responsibility and to grow.
I am a husband and father of two children who regularly find me running or cycling in the countryside. As the drummer of the band Eclectic Gems, I occasionally perform in music cafes or festivals to express my creativity.
As a citizen and professional, I value the concept of citizenship and the theory of the commons. We all have a responsibility towards each other and our society. Treating others as you would like to be treated yourself, is a golden rule that I hold dear.

These are the people at Respellion, a bit rebellious and with a great sense of responsibility for society.

The team

Developer

I am a passionate and social software engineer with several years of experience in full-stack development. I am proficient in various programming languages and frameworks, with my expertise focused on .NET combined with React or Angular. Additionally, I have knowledge of Azure Cloud and thoroughly enjoy working with it.
My enthusiasm for technology, attention to detail, and knowledge of various disciplines lead to efficient solutions. Colleagues describe me as hands-on and results-oriented. I highly value the &#8220;camping mentality&#8221;: I strive every day to leave the projects I work on in a better state than I found them.
My expertise goes beyond technical implementations; my focus is on sustainable, innovative solutions that successfully complete projects while also adding value and encouraging future developments. I enjoy working with diverse team members, where I not only produce code but also coach and support others in their professional growth. My commitment to team development contributes to a positive and collaborative work environment.
I live with my girlfriend in Rotterdam. In my free time, I enjoy tending to my aquarium, watching history documentaries, or meeting up with friends or family. Although I’m not a master chef, I have a great passion for barbecue.

Software Developer

From a young age, I became fascinated by computers thanks to my older brother, who was already involved in technology early on. My journey began with an Atari game console, MSX, and Personal Computers, and my interest has always remained technical. With education in Electrical Engineering, Electronics, and Computer Science, I have laid a solid foundation for my career.
As a skilled backend developer in the Microsoft stack, I bring technical expertise and passion together to create robust and efficient solutions. Collaborating with colleagues is my greatest motivation; finding the right solution together, brainstorming, and guiding other colleagues are aspects that fulfill my work.
In my free time, I listen to a lot of music, game occasionally, and often go for walks in parks on weekends. For vacations, I enjoy renting a cottage to explore the surroundings or taking road trips to visit various national parks.

Strategisch adviseur

<div class="card-body">
<div id="outputtext">
As an IT entrepreneur, I served as the director of QDelft since 2007 and successfully guided the rapid growth of the company to over 100 employees. In 2019, we became acquainted with the successful Danish company Netcompany, ultimately leading to the sale of QDelft. Subsequently, I was responsible as Managing Director to oversee the further development and integration of the Dutch business unit.
After completing my Computer Science studies at The Hague University of Applied Sciences, I chose to remain in the area and happily settled down with my family in the Duinoord neighbourhood.
I have extensive experience in acquiring, executing, and overseeing complex and large-scale software development projects, primarily within the public sector. With the knowledge and experience gained, our goal at Respellion is to articulate a vision for software development from the perspective of the public sector, ensuring that its core values are fully represented. The founding principles of Respellion are rooted in open-source, transparency, and a fresh and innovative approach to the software development process.

Test Consultant

After my studies in Public Administration at the Hanze University of Applied Sciences in Groningen, I got into software testing more or less by accident. I had always been interested in software and computers and during my studies I volunteered at my old high school to help out with computer classes. My enthusiasm for software and computers, especially for software testing, is still very strong, which is only natural with more than 20 years of experience.
My greatest pleasure comes from working with the team (with developers, testers, analysts and/or UX designers) to deliver high-quality software (of course as bug-free as possible) in order to have a satisfied customer.
My strength lies in creating and maintaining a good team spirit, in which everyone works well together and helps each other. I have participated in testing in many different roles (tester, test coordinator, test manager) and helped delivering many applications. In my spare time I like to be with my family, but I also enjoy sports (running, cycling and gym) and coaching/training my son&#8217;s soccer team.
As a test consultant, you must be able to think and act like the user of an application. And you must also be able to convey that to your team. Because only that way can you ensure that the customer is satisfied with the delivered application.
At Respellion, I hope to apply my testing knowledge and expertise to our mission: To strive for a society where open source technology is being used in a sustainable way for digital solutions.

Edwin van den Houdt

Technology Officer | Scrum Master

At Respellion, I am responsible as Technology Officer for developing and communicating the technology strategy! Over the past years, I have gained extensive knowledge in software delivery, innovation, and digital transformation. This role allows me to fully apply that expertise, along with my passion for technology and entrepreneurship.
From a young age, I discovered my passion for software engineering and entrepreneurship, which has shaped my career. Throughout my career, I have gained extensive experience working with government clients and managing projects with strict deadlines. My strength lies in collaborating with multidisciplinary teams to tackle complex challenges and create innovative solutions, particularly in areas with societal impact.
With a BSc in Computer Science and an MSc in Management of Technology, I bridge the gap between technical expertise and business value. This unique combination enables me to approach problems both technically and strategically, ensuring that solutions align with commercial objectives.
I believe that strong collaboration with stakeholders leads to better project outcomes. I am passionate about creating value through technology and delivering impactful projects. I am excited to contribute to Respellion’s mission of making a positive impact in the public sector through social responsibility, expertise, and open-source technology!

BI consultant

<div id="output" class="page-generator__output js-generator-output">
<div class="card-body">
<div id="outputtext">
I have a background in social science research, and after working as a researcher for several years, I specialized in developing computational models and Business Intelligence. I have always worked in small, agile organizations and have noticed that the flat organizational structure fosters a sense of equality and encourages easy collaboration among colleagues. This is also what we strive for at Respellion.
What attracts me to Respellion are the values of the group of people, whom I have gotten to know well over the past years. On one hand, they are highly responsible towards each other, the client, and society. On the other hand, they are curious and quite often a bit unconventional and innovative.
In my spare time, I enjoy going outdoors for a bike ride or doing volunteer work at the collective farm of which we are members of (<a href="https://vlinderstrik.herenboeren.nl">https://vlinderstrik.herenboeren.nl</a>).</div>
</div>
</div>

My journey into software development started in high school, almost by accident. A friend and I signed up for computer science classes together—she was drawn to the visuals, designing user interfaces, while I found myself fascinated by the logic behind it all. I loved figuring out how everything worked under the hood, and before I knew it, I was deep into coding. That curiosity led me to pursue an IT education, and I haven’t looked back since.
Over the years, I’ve grown into a full-stack developer with a strong focus on front-end. For me, a great interface isn’t just about making it look good—it should be structured in a way that any developer can easily understand and build upon. I love collaborating with others, sharing knowledge, and working as a team to create smart, efficient solutions.
But development isn’t just about writing code. I believe it’s just as important to understand how a project functions as a whole. When I can see the bigger picture, I’m able to think along with the business and uncover both functional and technical improvements that might otherwise be overlooked.
When I’m not coding, you’ll probably find me outdoors—hiking, snowboarding, or playing tennis. I also love reading and discovering new places whenever I get the chance to travel.

Enterprise architect

<div id="output" class="page-generator__output js-generator-output">
As an architect, I make complex technical issues understandable and clear. I can communicate effectively with both experienced developers and stakeholders such as clients and users. This communication works both ways: on one hand, fostering understanding among technical professionals about the interests of stakeholders, and on the other hand, explaining to stakeholders what is technically feasible. Drawing from my experience with complex projects, I&#8217;ve gained a deep understanding of potential possibilities and related risks.
My goal for the coming years is to focus more on structurally improving the digital government, particularly for citizens, businesses, and the government itself. In my view, this begins with more effective systems, standards, and building blocks. I see significant potential in Linked Data (semantic web) in this regard. Although I am aware from my experience, that there is still much work to be done. Through Respellion, I hope to make a positive contribution to this endeavour.
</div>

As a software developer, I discovered my passion for technology at a young age, when I was fascinated by the ins and outs of computers while my peers were enjoying playing games. My curiosity and eagerness to learn drive me to continuously take on new challenges and further develop my skills. Whether I work independently or in a team, I value collaboration and effective communication to arrive at the best solutions. My analytical and creative approach helps me develop software that is both functional and well-suited to the needs of users and the goals of the company. I strongly believe in automation because it performs tasks faster and more accurately, which reduces errors and saves time. I therefore always strive to automate processes where possible. At Respellion, I feel at home because the organization has a flat hierarchy and where collaboration and trust are central, which fits well with my way of working.
In my spare time, I like to explore open source technologies and enjoy playing various team sports such as basketball and padel. On sunny days I enjoy riding my motorcycle, while I also regularly go to the gym. I also like to try new recipes and discover new places to eat.

Architect | Developer

With experience in various projects for both public and private clients, I share my belief in technological innovation and improving our society. Working at Respellion feels like coming home, given the shared history I have with my colleagues.

I strongly believe in the crucial role of automation, with a focus on reducing human errors and optimizing the development workflow. With my experience, I lead and inspire my team, emphasizing collaboration and knowledge sharing.
In my spare time, I engage in open-source projects, collaborating with fellow developers to enhance software quality and give back to the community. Additionally, I enjoy reading to relax and explore new ideas.

At Respellion we strive to create an inspiring and innovative working environment where talent thrives and ideas blossom.
