Amadeusz Sadowski is an engineering leader with 13 years of experience building scalable .NET-based data platforms and analytical event pipelines, currently heading an engineering department at Allegro. He led a large-scale migration of 120+ .NET microservices to .NET 8 running on Kubernetes and designed a new generation of analytical event schemas that enabled automated validation and painless adoption across teams. Comfortable in hybrid, distributed environments, he routinely collaborates with Data Science, ML and Warehouse teams to turn product roadmaps into production-grade solutions. A pragmatic hands-on manager, he balances architecture, mentorship and implementation, often guiding less-experienced engineers through complex deployments. His open-source contributions to the Avalonia UI framework show attention to UI edge-cases and a willingness to improve ecosystems beyond backend systems. Based in Warsaw, he combines strong Azure and cloud-native experience with a master’s in computer science from Warsaw University of Technology.
