About Marc R. Leonard

I build video infrastructure at scale. Currently at Mux, where I work on the core services that ingest and process video for streaming platforms worldwide.I have a unique background: I started as a video director and post-production specialist before transitioning into software engineering. That foundation gives me a unique perspective on building tools that serve actual creators and media workflows.Over the past 8+ years, I\'ve architected video transcoding platforms, built cloud infrastructure across AWS and Azure, and shipped features that process hundreds of thousands of hours of content for OTT, broadcast, and cinema customers.I work primarily in Go and Python, specializing in video codecs/formats (H.264, HEVC, CMAF, fMP4), streaming protocols (HLS), and the infrastructure that makes it all scale. I\'m also deep into FFmpeg, libav, and media processing pipelines.When I\'m not working, I\'m building side projects like TimecodeTool (a timecode CLI), Asset Veranda (media asset management), and LineDream (a generative art library for Python). Or, ya know, skiing.Based in Bozeman, Montana. Always happy to connect with folks working on interesting problems in video, streaming, or media tech.
