Available to hire
Hi, I’m Maarten Reijmerink, a frontend-focused web developer from Amsterdam who believes in building accessible, impactful digital products for a better world. I enjoy turning complex requirements into clean, maintainable code and collaborating with teammates, designers, and other stakeholders to ship meaningful features.
Over the years I’ve worked on educational web apps, design systems, and open-source platforms, steering frontend projects from concept to production in collaborative workflows. I value mentoring teammates, sociocratic decision-making, and creating future-proof solutions.
