Rockstar🎓
Top SchoolBrett Kolodny is a Senior Software Engineer based in New York with nine years of experience building full-stack and blockchain-focused systems using JavaScript, Python, Java, C/C++, Rust, and Elixir. He has shipped production work across Web3 projects—contributing to Substrate-based runtimes at Acala and the Open Runtime Module Library—and improved safety and benchmarks by migrating storage types and adding weight functions and tests. Brett also bridges front-end and back-end concerns, from wallet UIs at enKrypt to backend adaptors for DeFiLlama’s yield-server and tooling improvements in Gleam and coder. He favors thoughtful refactoring and developer ergonomics, demonstrated by migrations to construct_runtime and Deno support for Gleam, and by adding concrete error handling and pagination UX fixes. Outside of code, he’s an amateur knitter, a detail that mirrors his patient, craftsmanship-oriented approach to software.
