Sebastian Vogelsang
With over 18 years in IT and a focus on open protocols, he helps organizations navigate decentralization and digital transformation. His current work centers on the AT Protocol (ATProto), building user-centric social apps and infrastructure around the shared Bluesky graph.
He leads Flashes, the photo and video app often called "the Instagram for the open social web," and co-develops Eurosky Social, a European initiative advancing digital sovereignty and public-interest infrastructure for ATProto.
Over the past 15+ years, he has contributed to more than 50 published apps, including award-winning titles featured by Apple and downloaded by millions.
As a full-stack engineer, he designs and builds native iOS and backend systems, with recent products like Flashes and Skeets for Bluesky showing how open protocols can power next-generation social experiences.
Accessibility is integral to his work — he develops inclusive, human-centered apps that work for everyone, combining strong technical execution with thoughtful UX and accessibility standards.
