Summary
🤩
RockstarMikhail Filitov is a Senior Software Engineer with 8 years of experience specializing in distributed systems and backend development, currently working on the open-source YDB distributed SQL database. He has a strong systems background from C++ at Yandex to cloud-native services and Lambda migrations at ABBYY, and focuses on performance, memory management, and reliability in large-scale systems. A Skoltech MS and HSE BS alumnus, he blends academic rigor with practical engineering, teaching computer architecture and OS courses at HSE while maintaining course notes and video lectures publicly. His contributions to YDB include compute actor work, spilling libraries, and refactors that improved throughput and memory behavior—evidence of deep low-level and database internals expertise. Based in Belgrade, he pairs hands-on coding with developer education and open-source engagement, signaling both production impact and a commitment to knowledge-sharing. An interesting non-obvious detail: alongside production work he creates tooling and educational content, making complex OS and architecture topics accessible to students and peers.
