Frederik Aulich
Fullstack Software Engineer — Crafting fast, privacy-first products — from APIs to AI-powered interfaces.
About
A few words
I'm Freddy — a fullstack software engineer building software products end-to-end. I care deeply about performance, clean architecture, and thoughtful UX. Lately I spend a lot of time integrating AI into real-world products — with a strong focus on privacy-first, GDPR-compliant setups using locally-running models that keep sensitive data off third-party servers.
