Johan Bachmann

ML engineer & pipeline builder based in Copenhagen.

I build machine learning systems, computer vision, image restoration, and data pipelines. Background in media production gives me hands-on context most engineers don't have.

About

I'm a Copenhagen-based freelancer working at the intersection of machine learning and media production. My focus is computer vision, image processing pipelines, and applied ML, built and shipped in Python.

I have a background as a film and TV production technician, I understand the workflows and problems I'm building tools for. Currently into adversarial ML and model optimization.
