I’m Jelle, a designer who codes. Currently on the product design team at DFFRNT Lab.


TicketSwap is a safe and fair place to buy and sell e-tickets. Ticket prices are capped at 120% of the original price and checked for validity. Currently TicketSwap has more than 5 million users worldwide which makes it one of the biggest fan-to-fan ticket platforms in the world.

Side projects

While working as a product designer during my day job I also focus a lot on coding during my side projects. In the past year I’ve learned how to use React, Electron and TypeScript while solving some productivity issues.
