Worked on backend and compiler improvements in the golang/go repository, focusing on stabilizing closure handling for type-converted closures in Go. Addressed a bug where unnamed closures wrapped in no-op type conversions were missing FuncInfo metadata, which previously led to linker issues and unreliable builds. The solution involved creating LSym entries for such closures, enhancing compilation reliability. Later, contributed to the ml-explore/mlx-lm repository by enhancing the command line interface with a new --prefill-step-size parameter, allowing users to tune generation performance. Leveraged Go and Python, applying skills in backend development, compiler design, and CLI development to deliver targeted, maintainable solutions.
