I’m Jelle, a designer who codes. Currently I’m working on Montro, a new marketplace for pre-owned luxury watches. Previously on the design team at TicketSwap, Europe’s biggest and fairest second hand ticketing platform.


Montro is a new marketplace for pre-owned luxury watches. I joined the startup as one of the first designers and helped define the design vision of the product. The projects are fully owned by one designer. From research to visual design, and from visual design to prototyping.

My main focus was to design the marketplace. I also worked on the design system, sellers and taxonomy part of the platform.


A safe and fair place to buy and sell e-tickets. With over 5 million users it is one of the biggest fan-to-fan ticketing platforms in the world.

The most impactful projects I’ve worked on are the raffle, event discovery and the native Android sell flow. I've also set up the design system for iOS, Android and Web so that we could easily grow the platform while keeping the experience experience consistent.


Most of my regular working days are focused on design. However, when working on a side project I mostly focus on code. It helps me to keep my front-end skills fresh while having some fun. Desize is a tool that helps you to quickly compress and resize large amounts of images.
