Full-stack engineer who ships end to end, from production LLM-agent infrastructure at work to a cross-platform desktop app with its own community. TypeScript and Go, with deep AI-agent integration experience.

Agent-first by habit: parallel Claude Code sessions in isolated git worktrees, Herdr to keep tabs on them, VS Code for reading code and reviewing the diffs they produce.

Projects

Slack-native engineering agent

Pendo

Takes a ticket, works the codebase, opens the pull request

An agent we call Hork, built 0 to 1 and working across a multi-repo codebase. It picks up new bugs as they're filed and jumps on CI failures on its own; an @-mention points it at a specific ticket. Bug triage came first, then smaller feature work.

Each investigation is a live session bound to a Slack thread, not a one-shot prompt. Reply to redirect it mid-run, add context like screenshots or logs, or approve the pull request it's offering.
