Hi, I am Lars
Senior full-stack developer at 
Adswag, a digital advertising company in Amsterdam. I lead technical projects end to end, from the first architecture sketch to the last deploy, and I like the problems best where hardware, data and software meet.
Outside work you'll find me on a motorcycle, on a kitesurf board, or at home wiring up ESP32 boards and printing parts for whatever automation idea I had that week. At Adswag I build in TypeScript and Go, with 
React on the front and 
NestJS and 
Go services on the back. It all runs on 
Docker and 
Kubernetes, is automated with 
Ansible, and AI agents have become a normal part of how I work.
