Jonas Grunau
About
Hi, I’m Jonas — a software developer from the Munich area.
I got hooked on programming as a kid and never stopped. Development is not just my job, it’s a genuine passion — I spend my free time exploring the newest technologies to stay on the cutting edge.
I spent four years as a Lead Developer, designing and shipping projects with Angular, React & Node.js, and Flutter & Firebase together with my teams. I care deeply about clean, maintainable, scalable code — software that’s built to last.
I also work extensively with AI — above all Anthropic’s Claude: Claude Code is part of my daily development workflow, from pair-programming and code reviews to building agentic automations.
Good communication, teamwork and a structured approach are essential to how I work, and continuous self-driven learning keeps me at the pulse of the industry.
