Senior Fullstack Developer & Embedded Engineer

maker. techy. entrepreneur. soft- and hardware enthusiast.

With nearly two decades of experience, I enjoy bridging the gap between software and hardware, loving both worlds equally. Passionate about coding, leadership, and sharing knowledge.

I'm an AI early adopter and power user — from coding agents like GitHub Copilot, Antigravity, Codex, and Claude Code, to fully autonomous agents like OpenClaw, and automation platforms like n8n and make.com. I leverage these tools daily to stay at the cutting edge and maximize productivity.

Creator of the famous 'slaesh CC2652RB (ZigBee) stick', shipped to thousands of smart-home lovers all over the world.

My expertise extends to professional-grade prototyping, PCB design, 3D printing, and CNC machining.

This is just an overview, I can do anything if I am passionate about it, so just get in touch! ;)
