Software Craftsman

I build things for people who build things.

Portrait of Tristan Teufel

About me

I'm Tristan, a freelance software craftsman based in Bühl, Germany. I've been developing software for more than 15 years.

To me, good software is a craft: readable code, fast feedback loops and tools that make developers' lives easier.

You'll find an overview of my current projects on GitHub.

How I can help you

Four areas where I add the most value to teams.

Developer Experience & Tooling

Fast builds, clear monorepo structures with Nx and tailored editor and CLI tools: I remove friction from your developers' day-to-day work.

Test Infrastructure & Strategy

I build test suites with Vitest, Playwright and Jest that run reliably, give fast feedback and make releases predictable.

Modernization & Clean Code

Incremental refactoring instead of a big bang: I move legacy code to a maintainable architecture following SOLID & KISS – backed by tests.

AI-Augmented Engineering

I integrate agent-based workflows such as Claude Code into your development process – with clear guardrails, reviews and tests.
