Summary
👤
Senior🎓
Top SchoolClaus Colloseus is a frontend web developer based in Berlin with 12 years of experience specializing where JavaScript, SPAs and Node.js meet rich visualizations and animations. He brings deep expertise in SVG—over a decade of hands-on work and community support on Stack Overflow—and publishes open-source Node modules and contributions to desktop projects like the Cinnamon applet ecosystem. As a freelance developer since 2019, he combines practical full-stack fixes (modernizing APIs, improving UX) with a background in WordPress and institutional software, and he’s comfortable refactoring legacy code into modern patterns. His unusual blend of physics/history academic training and long-term SVG specialization gives him a thoughtful, analytical approach to front-end design and interaction.
