Simon Boisset, Freelance software developer, web & mobile
Trained physicist, I spent five years in the laser industry before making software development my job. Since 2020 I have worked professionally, first inside startups, then as a freelancer for startups and SMEs, on web and mobile apps. Alongside, I build my own products.
