Top SchoolSviataslau Hankovich is a Principal Backend Engineer based in Amsterdam with 9 years of experience designing and operating high-scale, resilient systems that handle 50K+ RPS and serve 20M+ monthly users. He specializes in C#/.NET, distributed architectures (DDD, CQRS/ES, event-driven), Kubernetes, Kafka and cloud-agnostic deployments across Azure and AWS, and has repeatedly cut costs and improved reliability through pragmatic architecture and caching. His work spans gaming, streaming and healthcare—architecting a gaming platform that processes €40M+ annually and modernizing critical NHS-adjacent systems with zero downtime during cloud migration. An open-source contributor to the popular CSharpFunctionalExtensions library, he brings practical improvements for async patterns and Result/Maybe ergonomics used widely in the .NET community. Former assistant lecturer with a Master’s in algorithms and big-data processing, he pairs hands-on delivery with mentoring and building engineering culture, having grown teams while keeping startup velocity. He’s particularly skilled at applying actor models (Orleans) and event sourcing in production to solve real-time and revenue-critical problems.
