🤩
Rockstar🎓
Top SchoolYuri Iozzelli is a compiler engineer based in Amsterdam with 14 years of experience building and maintaining tools that translate native code to web-friendly runtimes. At Leaning Technologies he works on Cheerp/CheerpJ, shipping compiler-level solutions that enable large C/C++ and Java codebases to run as WebAssembly/JavaScript in browsers. His open-source contributions show a practical balance of systems and full-stack work—from fixing low-level bugs in the P4 behavioral model to integrating Tailscale and improving Go WASM loading in a WebVM project—demonstrating attention to cross-platform compatibility and developer experience. He combines strong academic credentials (top honors in Computer Engineering) with hands-on systems administration and tooling experience from academic research labs. Colleagues describe him as someone who quietly improves robustness and interoperability across compiler, networking, and web layers.
