Open Source Developer
Building LLM infrastructure, platform tooling, and container-native CI/CD. Author of Franky (streaming LLM agent framework), zompress (token compression), and engine-ci (container-native CI/CD).
- franky — A provider-agnostic, streaming LLM agent and framework written in Zig
- engine-ci — Reduced per-project CI setup from hours to minutes by building a container-native pipeline engine in Go (103 releases) that runs identically locally and in CI via Docker or Podman
- DuneBot — Eliminated 10+ hours/week of manual Dependabot PR triage by building a GitHub App (20 releases) that automates approvals and dependency merges
- Authored a 4-part tech blog series (12K+ reads) documenting the journey from GitHub Actions frustrations, through Dagger.io evaluation, to building engine-ci
- go-file — Published a Go file abstraction package with lazy initialization, buffer I/O, and test-friendly error injection for simplified file testing

2001 - 2006
After reading the book 'Principles' by Ray Dalio. I was inspired to put together my personal working principles.
Meeting
- Don't take the time and attention of work colleagues for granted.
Change
- The power of change and adaptation starts with yourself.
Efficiency
- Just work smart — break repeating cycles, focus on the ratio of time and outcome.
Tools / People
- Tools have to follow people, not the people the tools.
Leadership
- It's not about you — focus has to be on the people to lead, help them to grow.
- It's all about you — be authentic and lead by example.
