Software engineer at GitHub, working on agentic coding tools.
Originally from Cologne, now in the Pacific Northwest. When not coding, probably on a mountain somewhere.
Work
GitHub-native desktop experience to start agentic development from the work in front of you, keep it isolated, steer it as it goes, and land the change through pull request review.
Autonomous coding agent that picks up issues, opens pull requests, and iterates on review feedback — with cloud-hosted execution and integrations across GitHub, Slack, and Teams.
CI/CD and automation platform built into GitHub. Helped launch and scale from zero to millions of workflows per day.
Playground and API bringing industry-leading AI models to 100M+ developers on GitHub — experiment, compare, and deploy from playground to production.
Side projects
Durable workflows for Go similar to DTFx/Cadence/Temporal. Supports different backends (MySQL, SQLite, Redis).
VS Code extension for GitHub Actions workflows and runs.
Interactive tutorial and visualizer for GitHub Actions workflows.
Free browser game inspired by the "world domination" board game. Play with your friends on many different maps.
I'm a Staff Software Engineer at GitHub, where I'm working on the GitHub Copilot app. I care deeply about developer experience and building tools that get out of your way. Originally from Cologne, now somewhere in the PNW chasing summit views.
