Worked on backend and blockchain development using Go, focusing on enhancing data integrity and reliability across the ava-labs/avalanchego and ava-labs/libevm repositories. Built a feature in avalanchego to verify external data hashes within the SAE VM, ensuring that block extData matches the committed header hash and updating block parsing logic with comprehensive tests. Addressed a concurrency issue in libevm by replacing the snapshot generator’s abort mechanism with a stopGeneration method, improving shutdown reliability and aligning with upstream changes. Demonstrated skills in Go, concurrency management, and test-driven development, with careful attention to cross-repository compatibility and robust maintenance workflows.
