Summary

Senior🎓
Top SchoolJan Hettenkofer is a freelance software engineer based in Munich with eight years’ experience building image- and video-focused systems from prototype to production. He blends practical software engineering—APIs, internal tools and real-time pipelines—with deep domain knowledge in colour science and image quality, having implemented ISPs and ultra-high‑frame‑rate video generators. Past roles span startups and embedded/media companies where he shipped GPU-accelerated prototypes, GStreamer plugins, REST APIs and DSL processing operations, and even volunteered as a Scrum Master. His background in computer science and electrical engineering informs a hands-on approach to low-latency capture, image processing workflows and perceptual quality problems. Outside code he still makes “pretty pictures” with cameras and algorithms, bringing a photographer’s eye to technically rigorous solutions.
