Engineer at GitHub handling deepest-tier (L3) escalations. I contribute production code to the Rails monolith, build and deploy internal tooling, and turn customer pain into shipped fixes.
About
Engineer with an MSc in Physics and a systems-debugging background. I ship production code, build internal tooling, and reason about security, accessibility, and rollout risk — using AI as a force multiplier, but keeping the judgment my own.
Contributing to github/github, GitHub's Rails monolith — Ruby, ERB, view-model refactors, and test coverage.
Resolving L3 escalations, including production-down debugging of GitHub Enterprise Server.
Building and deploying full-stack dashboards and CI/CD automation that scale across the org.
Driving remediation of production vulnerabilities and building accessible, ARIA-correct UI.
Selected Work
A sample of engineering work — every claim traceable to a real, verifiable link.
Authored a production-targeted PR to github/github restructuring the GitHub App permission-consent screen into accessible, resource-grouped sections — view-model refactor, ERB, ARIA semantics, and a feature-flag rollout plan.
Identified and drove remediation of a production vulnerability allowing unauthorized access via private GitHub Apps — protecting hundreds of enterprise customers.
Built and deployed a full-stack internal community dashboard (GitHub Pages + OpenAI API) used within the support org.
Developing an internal tool that maps GraphQL endpoints to their required permission scopes, cutting investigation time for engineers.
Merged PRs to github/github improving the Copilot metrics schema and code-scanning API descriptions.
Implemented a docs-update automation workflow and authored additional CI/workflow automation for support tooling.
Journey
A snapshot of the path that brought me here.
Resolving deepest-tier engineering escalations, contributing production code and automation to the monolith, and serving as the GitHub Apps / ecosystem SME in engineering triage.
Led architecture and full implementation of a government-funded IoT platform. Built backend services and data pipelines (Python, Docker) and served as Scrum Team Lead.
Trained in analytical thinking and systems problem-solving at one of Germany's top research universities.
