Hi, I'm Jan

A pragmatic software engineer from Germany. PHP and Symfony veteran with a preference for DevOps, testing, and code quality.

Extra ingredients: software architecture, mentoring, consulting, development lead, team lead, people lead, python, IoT

I build systems using PHP/Symfony, Docker/Kubernetes, and modern CI/CD practices, while exploring how AI/LLM can streamline development and operations.

  • 🔭 I’m currently working with PHP, Symfony, containerized systems, Kafka, and Caddy.

  • 🌱 I’m currently expanding my capabilities in AI tooling and LLM workflows.

  • 🎹 In my free time, I enjoy bread baking, learning piano, and the harmonica.

  • 💬 Ask me about PHP, Symfony, software engineering, security, observability, DevOps, containerization, Caddy, PHPUnit/testing, and Linux.

  • 📫 How to reach me: jan@markmann.dev

  • 📄 Want the full story? Here’s my resume: https://markmann.work/resume/

  • ⚡ Fun fact: in theory, music is pure logic.
