Developer-tool reliability engineer. Open-source contributor. Builder of small fixes with outsized leverage.
I work on the sharp edge of agentic engineering: usage meters, CLI integrations, runtime boundaries, editor state, config behavior, and docs systems. When a developer tool quietly wastes time, I trace the failure, ship the narrow fix, and prove it with tests.
29 public upstream pull requests merged since February 2026.
My bias: maintainers should see the issue, trust the diff, and merge without babysitting.
Canonical profile | Pull requests | LLMs.txt
- CodexBar - 16 merged PRs across usage metering, provider history, config paths, docs integrity, and CLI edge cases.
- OpenClaw, Crabbox, gogcli - runtime boundaries, sandbox/session behavior, and docs validation.
- Plate - editor UX fixes where table and MDX behavior needed precise state handling.
- Rueidis and Rushstack - package and systems tooling fixes with small, reviewable changes.
- Vercel AI, Langflow, MCP TypeScript SDK - active upstream work in AI workflow and protocol tooling.
- Usage and billing accuracy across real CLI behavior
- Provider parsing, fallback paths, cache behavior, and subprocess boundaries
- Config diagnostics that tell the truth without surprising users
- Narrow PRs with clear behavioral proof
- Tests that protect the actual regression

- Reproduce before diagnosing.
- Understand the product surface, not only the failing line.
- Keep the diff small enough to review seriously.
- Add tests where the bug could come back.
- Write PR notes that make the maintainer's job easier.
- Leave the codebase calmer than I found it.
- Tightening usage and cost visibility for AI developer tools
- Hardening CLI, config, and runtime boundaries
- Contributing focused fixes to high-signal upstream projects
- Building research systems where claims can be traced instead of guessed
Small diffs. Real tests. Clean PRs.
I do not chase large diffs. I chase leverage.
