📍 Bühl, Germany | 💻 Software Craftsman | 🏢 Teufel IT

I’m a Software Craftsman with a focus on architecture and developer experience. I enjoy building things that make development less painful and systems more resilient. Currently doing some heavy lifting in enterprise environments, but always keeping my hands dirty with Open Source.

I help companies bridge the gap between complex requirements and maintainable, high-quality software. With a decade of enterprise experience and deep developer tooling knowledge, I make your codebase an asset, not a liability.

How I can support your team:

• Architecture & Strategic Consulting: expert feedback on system design and scaling modern software ecosystems.
• Modernization & Refactoring: migrate legacy codebases to modern, clean, testable, high-performance stacks.
• Developer Experience & Tooling: build testing and automation infrastructure, drawing on years of maintaining developer tools with over 2 million installs.

📅 Available for new projects from January 2027.
