Open Source
When something breaks, I fix it and send the patch back.

OpenAI's coding agent CLI. Fixed file search, paste handling, and elicitation bugs.
Open source scheduling. Fixed CalDAV duplicate invitations and iCalendar output.
GitHub's official CLI. Added --exclude flag to pr diff, --squash-merge-commit-message to repo edit, changeType field, and deduplicated scope errors.
Expensify's mobile app. Fixed navigation animations, popover bugs, and playback sync. $750 in bounties.
Replaced unsafe innerHTML with safer DOM APIs. Security issue surfaced by vibecheck.
About Me
i build backend-heavy ai systems at august. the work is messy in the good way: health data, document pipelines, llms, real traffic. i like tools that are sharp, fast, and readable. i ship open source and have very little patience for vague abstractions.
i work best in small teams where i can own systems end to end. i optimize for fast feedback loops, clear interfaces, and small bets that compound.
