Summary
👤
Senior🎓
Top SchoolKirill Berezin is a Site Reliability Engineer with 13 years of full-stack and systems experience, currently focused on SRE at RingCentral from 2020 onward. He blends deep graphics and GPU expertise (OpenGL/GLSL, WebGL, OpenCL) with backend and DevOps skills—Node.js, Postgres/NoSQL, Kubernetes and GCE—to build high-performance, latency-sensitive distributed systems. His background spans HPC and big data (OpenMP, Hadoop/GBQ), real-time networking (sub-millisecond RT, P2P) and early blockchain community involvement since 2010, giving him a rare mix of low-level performance tuning and product-minded delivery. He has led backend teams building high-throughput payment/messaging platforms and run a fast-paced e-commerce venture that optimized order-to-door workflows to near-instant delivery. Comfortable across OSI layers and GPUs, he prefers backend reliability work but can implement complex GPU-only effects when needed.
