I have been working with Wijnand together on a MVP for a startup in React-Native. He has a genuine interest in programming and is always looking for ways to improve his code, make workflows more efficient and has very in-depth JavaScript knowledge. Also he is very goal-oriented and is very focussed on reaching his goals and embodies a "get it done" mentality. Highly recommended for your next MVP or React application!
