Hi, I'm Felix 👋

Software engineer working across systems programming and backend/infra tooling. I like working in complex systems and making the kind of change that meaningfully simplifies them and makes them more resilient — not just adds another layer. I trust stats and numbers over gut feeling, and I'd rather spend time finding and fixing the root cause of a problem than patch the symptom and move on.

What I work with

Professional

  • Languages: TypeScript, Go, Kotlin
  • Actively used (last years): SpringBoot, Express/Hono, AWS + CDK + CloudFormation, Prometheus, Grafana, SOAP, OTEL, CodePipeline, GitHub Actions
  • Experience with, less recently: Kubernetes, Keycloak, Angular, Svelte, Ansible, Concourse, Python

Private

  • Languages: Rust primarily, also experimented with Haskell, C, Java
  • Currently: agents and agent sandboxing
  • Historically: light embedded work, self-hosting, coding puzzles (Advent of Code, LeetCode)
