Summary
🤩
RockstarComputer Scientist with seven years of engineering experience based in Los Angeles and a USC Computer Science background (Class of 2022) who bridges research environments and production-quality tooling. Skilled in test automation and CI, they strengthened the testing infrastructure for the widely used rlworkgroup/garage reinforcement learning toolkit—adding doctests, hardening GitHub Actions workflows, and preserving important numerical logging across CPU/GPU runs. Comfortable working at the intersection of research labs (INK Lab, RESL) and engineering, they bring a researcher’s attention to reproducibility together with pragmatic QA practices that prevent regressions in complex ML codebases. Notably, they focus on reliability and maintainability in open-source ML projects, turning brittle experimental code into dependable components for the broader community.
