I am an independent software builder in Los Angeles. I make desktop software, developer tools, and research tools around focused problems.
- launchdx diagnoses macOS app launch failures from local signing, quarantine, and installer evidence.
- Tempo provides immutable date and time types for TypeScript.
- BoundaryBench studies authorization preservation in tool-using agents. Its deterministic harness is separate from model observations.
- Open Agent Skills contains standalone instructions for coding-agent work.
- env-clinic compares environment files and reports missing, extra, and empty variables.
More work is in the repository list and on my website.
