Open Source

Hebbian Robotics (YC S26) — hflow

Aug 2026 – Present

Open Source Software Engineer · Remote

  • Merged 12 PRs in the first public week of hflow, an open-source Physical AI data platform (Python, MCAP, DuckDB, Parquet). Reference: Kingston Kuan, Co-founder.
  • Fixed two silent data-corruption bugs: NumPy scalar measurements stored as NULL (episodes silently excluded from training manifests), and measurement keys shadowing episode columns (DuckDB silently renames; SELECT returns the wrong value). One discovered by auditing storage against curation queries, one reported by the co-founder. Both filed with runnable repros and merged same-day.
  • Shipped a LeRobot-to-MCAP converter passing strict format conformance checks, and a reproducible synthetic stress framework adopted as the repo's benchmarking standard (byte-identical episode files across runs).
