Summary
Sebastian Gebski is a seasoned engineering leader and principal solutions architect with 11+ years of senior experience building and scaling product and service technology organizations up to 70 people and shaping delivery pipelines for factories of up to ~300 developers. He combines hands-on system design for web, mobile, microservices and petabyte-scale analytics with pragmatic people leadership proven in rapid-growth, high-attrition recovery, regulatory-deadline and MVP/PMF scenarios. His career spans CTO and head-of-technology roles at fast-growing startups and global teams at AWS, where he advised startups across EMEA on architecture, scaling and cloud adoption. Sebastian is highly credentialed (AWS Pro, Data Analytics, PMP, PSM III, TOGAF) and fluent across stacks (.NET, Java, Elixir, Python) and distribution models from co-located to multi-site/offshore. He runs a consultancy and a community (No Kill Switch, CTO Morning Coffee) that reflect his interest in engineering culture, lean delivery and technical storytelling. Not obvious from titles: he pairs enterprise-grade rigour with developer empathy—often publishing on architecture and leadership—and enjoys shipping code and blogging in parallel to executive duties.
