Rockstar🎓
Top SchoolVsevolod Stakhov is a systems engineer and founder with 20+ years building high-performance, secure infrastructure in C, C++, Rust and Lua, currently focused on AI performance plumbing at AMD and leading RSPAMD LTD. He created Rspamd, a widely deployed open-source spam filter that processes over a billion messages daily, and authored libucl and a SAT-based solver used in FreeBSD packaging. His work spans low-latency trading systems at Citadel, Polkadot networking enhancements at Parity (including grid topology routing and observability tooling), and production-grade anti-spam platforms at Mimecast. Comfortable from kernel drivers to distributed analytics, he combines deep applied cryptography and TCP/IP expertise with practical ML and LLM integration for cost-effective inference. A PhD-trained researcher and frequent conference speaker, he blends academic rigor with hands-on product delivery and a knack for turning research ideas into widely used open-source tools.
