I maintain the Exivity API. love writing clean, reusable and maintainable code following coding standards and using design patterns.

In my free time, I love to go camping and explore new places. When I get home, I enjoy memory keeping and scrap booking my adventures. And anything involving beer.

I make sure the Exivity API is running smoothly.

Working on developing software for people or companies in Finance, HR and IT in the last 10 years, I am an professional Backend Developer with some mixed feelings about Frontend. But I learnt to never say never.

My spare time is a combination of spending quality time with family and friends, working for open source projects and playing handball for U.S. Amsterdam.

Stefan Wullems

Frontend developer

I started out as a fitness trainer. Making the switch to development was hands down the best decision I have ever made. Witnessed and contributed to Exivity's ongoing grow in maturity.

To unwind, I like to play classical guitar or listen to music. Next to that, I work on challenging side projects using new programming languages and technologies.

Having over 15 years of experience with IT consulting at enterprise organisations around the world, I'm a pragmatic and result oriented IT professional. At Exivity I'm in control of our roadmap and making sure the development priorities are set right. In addition to being the Scrum Product Owner, I'm leading a team of highly skilled Solution Architects to give our clients a world class onboarding and customer support experience.

In my spare time I like to ride long distances on my road bike on the "Dutch mountains" as well as the Alps ;-).
