I run Advance Labs. I came to Canada from a military boarding school in Poland, and now I build open-source software that developers and AI agents actually use. We build shit until it works.

Ninebrains · desktop app for running several Claude Code and Codex agents at once, each in its own git worktree, with gates that prove the work before it counts as done.
_{Apache-2.0 · macOS, Windows, Linux · ninebrains.runs-on.dev}

runs-on.dev · free yourname.runs-on.dev subdomains for developers. The public repo is the registry, so every claim is a commit anyone can read.
_{AGPL-3.0 · 1,200+ names claimed · 432 tests · runs-on.dev}

AEO Toolkit · scores a site the way an AI assistant reads it. Free in the browser, as a Chrome extension, and over MCP; the engine behind our paid audits.
_{Apache-2.0 · 54-rule engine · 988 tests · advancelabs.dev/tools}

urban-drone-autonomy · sim-first autonomy for a multirotor, flown through five real OpenStreetMap cities; it infers powerlines from the poles carrying them. Fly it in your browser.
_{275 tests · first PX4 SITL flight done, full missions next · Apache-2.0}

Upstream · two PRs to Pane (#572, #573): pane activation from 675 ms to 332 ms, plus inline renaming and the store bug behind it.

whoopsie-protocol (reverse-engineered WHOOP 4.0 BLE) · agent-handoff-protocol (move a running agent between hosts) · quantum-hybrid-research (quantum × classical feasibility, 228-test emulator) · athena-weather-mcp · 75-day-tracker

Advance Labs also takes a few fixed-price jobs: AEO audits and build sprints, with case studies here.
