Rockstar🎓
Top SchoolAlexander Emelin is a software engineer with 14+ years building high-performance backend systems and real-time infrastructure, currently working at Exness from Limassol, Cyprus. He has driven WebSocket and streaming features at Grafana Labs and contributed performance-critical improvements to widely used open-source projects like gorilla/websocket and the Centrifuge real-time library. Previously a lead engineer at Avito and long-tenured developer at Mail.Ru, he combines practical production experience with a physics-engineering background from MEPhI. Alexander’s work emphasizes latency, reliability, and efficient transport layers—often surfacing as non-obvious optimizations in compression, write paths, and command handling that materially boost throughput and stability.
