Rockstar🎓
Top SchoolPiotr Monwid-olechnowicz is a founder and software engineer based in Wrocław with a decade of experience building developer tooling, front-end systems, and TypeScript-first libraries. He’s shipped production-grade open-source projects — notably DethCode (a VSCode in-browser tool for inspecting deployed Ethereum contracts) and contributions to widely used ecosystems like DefinitelyTyped, theme-ui, and react-three-fiber — demonstrating deep expertise in types, DX, and web3 integration. As a former engineer at Edge & Node and L2Beat and now lecturing on startups and product development, he blends hands-on engineering with practical mentorship and product thinking. Colleagues describe him as a “software gardener”: someone who cultivates maintainable, type-safe code across the full stack and surfaces developer-friendly workflows that often solve non-obvious cross-platform and build-system challenges.
