Senior🎓
Top SchoolPavel Cherenkov is a Senior Software Engineer with 14+ years building high-performance server-side systems, specializing in IPTV streaming, low-level C development, and Unix-based production environments. He has deep expertise in video transport and encoding technologies (MPEG-TS, H.264, HLS/DASH), network protocols (UDP/RTP/IGMP), and multimedia toolchains like ffmpeg/libav, applied across products such as Gigapxy and udpxy. Pavel also brings solid database and performance-tuning experience (Oracle, MySQL, KDB+, Redis) and has contributed low-level optimizations to the Tarantool project, including an SSE4.2-accelerated CRC32 for WAL performance. Comfortable across Linux and FreeBSD, he combines systems programming (ANSI C, Lua, shell, Perl, Python) with practical operational know-how for STBs and server backends. His background spans finance, large-scale web services, and embedded/networked appliances, revealing a knack for squeezing predictable performance out of complex I/O-bound systems.

Contributions summary:Pavel focused on implementing and optimizing low-level system components within the Tarantool database. They introduced hardware-accelerated CRC32 calculations by leveraging SSE 4.2 instructions, which improved the performance of data integrity checks in the WAL writer. The contributions involved modifying core system files like `cpu_feature.m` and `log_io.m` to enable and utilize the new hardware features, and refactoring the codebase for style.
