Rockstar🎓
Top SchoolJonas Birmé is a seasoned streaming technology leader and CTO based in Stockholm with 12 years of professional experience and a MSc in Computing Science. He blends hands-on engineering and product leadership—transitioning from building HLS/DASH player and parser features (including SCTE35 support and TTML subtitle fixes in popular open-source projects like Shaka Player and m3u8) to guiding R&D and open-source strategy at Eyevinn. Known for architecting cloud-based video streaming and ad insertion solutions, he routinely converts proof-of-concepts into production-ready systems while fostering developer communities. Jonas combines deep protocol- and player-level expertise with practical team-building experience from managing distributed engineering groups, and he still surprises peers by having “stopped writing code manually” while remaining deeply technical and influential in streaming OSS.
