> BIOGRAPHY
Hey! I'm Marcel, also known online as Yamura. I build browser tools, creator software, and experiments that ship. My recent work includes Pyttig, a Python-first IDE that runs in the browser, and Renderdragon, a Minecraft creator tool that reached 12,000 unique visitors in its first month.
I work across React, Next.js, TypeScript, Python, Rust, and WebAssembly. I use AI tools when they make iteration faster without replacing engineering judgment. Based in Belgium and comfortable working in French, English, and Dutch.
