Top SchoolAlexander Bocharoff is a seasoned machine learning and systems engineer with 16 years of experience building ultra-low-latency, high-throughput infrastructure in Rust, Go, and Python. Currently at xAI after a long tenure at Cloudflare, he led ML-driven security products that process tens of millions of HTTP requests per second, developed the BLISS memory-first feature-serving platform, and delivered multi-year savings in compute through aggressive performance optimizations. He combines deep systems design (ClickHouse, Kafka, Rust memory-mapped serving) with hands-on model engineering and product ownership, shipping features like JA4 Signals and ML explainers that improve detection and customer transparency. A pragmatic tech lead and mentor, he has a patent for inter-process ML feature serving and maintains popular open-source Rust crates used for high-performance inter-process data access and cardinality estimation.
