Full-stack dev in Hamburg. IoT by day, side projects by night.

##Day job

By day I'm a developer at Bucher Municipal AG. Together with my team I build Bucher Connect, an award-winning IoT and fleet-management platform that gives operators of street sweepers a real-time cockpit for monitoring and maintaining their vehicles.

##Side projects

Outside of work I help small businesses move processes online, integrate AI into existing tools, and support startups in turning ideas into shippable products.

Recent things I've built on the side: Active Circle (a sports-event discovery platform with AI search), Heizkostenvergleich24 (heating-cost calculator), Hundekunde Pro (mobile study app), and Patto (a small Flutter game I use as a sandbox for new frameworks).

##Toolkit

Flutter · Vue · Django · Flask · Firebase · Firestore · TypeScript · Python · Astro · Cloud Run.

##Logged off

When I'm not coding you'll find me out kitesurfing, riding my road bike, or playing beach volleyball.
