Summary
👤
Senior🎓
Top SchoolValentin Bartenev is a seasoned systems and network software leader with 14+ years building high-performance web and application servers, currently heading development of Angie, an Nginx-derived server and its commercial variant. Deeply proficient in C and low-level systems (OS kernel, CPU, async/event-driven and lockless programming), he has driven core contributions to NGINX—especially HTTP/2, a fastest HTTP parser, and the NGINX Unit project that integrates multiple language runtimes. He blends hands-on architecture and implementation with product leadership: setting roadmaps, managing distributed teams, and running regular public release cycles. An active open-source contributor, his work appears in flagship projects like nginx and njs where he implemented protocol-level fixes and modern JavaScript features. Not obvious from job titles: he routinely implements low-latency shared-memory IPC and high-throughput connection limiting mechanisms used in production at scale. Based in Moscow, he combines deep systems expertise with practical product delivery and community-facing collaboration.
