Right now, he's hard at work building his second company, Stypt — an all-in-one software as a service solution to help businesses small and large manage their customer appointments. He also works as a creative front-end developer at Yummygum, a design agency in Amsterdam that helps startups and established businesses to refine, design and build their digital products.
