Summary
👤
Senior🎓
Top SchoolStephan Aßmus is a seasoned C++ software developer with 21 years of experience building multimedia and graphics-focused end-user applications and scalable backends. A core contributor to the Haiku open-source operating system and longtime maintainer of its media stack, he has deep expertise in audio/video playback, synchronization, and low-level system integration (including notable work on Haiku's MediaPlayer and app_server). He pairs product-facing UI tools—like vector editors and script/animation software—with rigorous backend design, having led projects from YellowBites’ WonderBrush to IP-TV and script-structuring tools at DramaQueen. Now at SAP while still active in Haiku development, he balances enterprise work with open-source commitments and family life—a shift reflected in a recent slowdown in GitHub activity. His background in animation and early graphics tooling informs a pragmatic, performance-minded approach to multimedia software engineering.
