Hi, I'm Matthias 👋🏻

Portrait of Matthias

I am a Software Engineer with a strong focus on Node.js, TypeScript, developer tooling and REST APIs, with professional experience since 2018. My work centers around building robust and reliable APIs and systems as well as CLI tools that enable efficient and reliable software development. Over the past years, I have developed a particular specialization in HTTP and REST API design and development. Both professionally and privately, I contribute to open-source projects such as Thymian and Fastify. You can follow my work on my GitHub profile.

With the rise of increasingly complex and distributed systems, I see reliable API behavior and protocol correctness as a critical foundation for modern software. This importance is further amplified by the growing adoption of agentic AI, where systems autonomously interact with APIs and depend on predictable and well-defined interfaces. As development speed continues to increase, ensuring correctness, observability, and confidence in systems becomes more challenging—and more essential.

In addition to my core focus areas, I have experience working with Java and Kotlin, as well as developing customized chatbot solutions. I have also been involved in product development and strategic decision-making, contributing to the definition of features, priorities, and overall product direction.
