I build high-performance systems: distributed storage/query engines, low-latency networking, and compiler/toolchain experiments in modern C++.
- PhD in Computational Mathematics
- Previously at Yandex: worked on multiple large-scale projects, including YTsaurus and YDB
- Since early 2020: focused on YDB SQL subsystem, working on a distributed SQL engine (execution/runtime & related infrastructure)
- Currently: HFT fund
- C++20/23 (coroutines, templates, performance-oriented design)
- Compilers / toolchains (parsing, semantic passes, IR, LLVM codegen/JIT/AOT)
- Low-latency networking (async I/O, event loops, transport abstractions)
- Distributed systems (fault-tolerance patterns, replication, consistency trade-offs)
- SQL / query engines (execution pipelines, distributed execution)
- Performance (profiling, concurrency, CPU/memory efficiency)
- GPU / graphics (graphics pipelines, compute/experiments)
- Also used in production: Python, Scala, Java
- fdm — long-running (15+ years) finite-difference / computational work
