Rockstar🎓
Top SchoolJohn Adler is a systems-minded software engineer with 13 years of experience and a deep C++ and compiler focus, now contributing heavily in Rust across Web3 and blockchain projects. He has driven core language, parser, semantic analysis, and codegen work for Sway and helped implement protocol and VM features in Fuel’s Rust full node and SDKs, showing strength in compiler internals and virtual machine design. Comfortable across the stack, he’s implemented both smart-contract backends and frontend pieces for a high-performance DEX, and has improved CI, testing, and automation to keep large open-source projects production-ready. Academically grounded with advanced ECE degrees from the University of Toronto, he pairs rigorous research instincts with pragmatic engineering discipline. Obsessed with clean, maintainable code and tooling, he’s currently weighing a deep dive into Rust or Go to broaden his backend and systems toolkit.
