SUMMARY
C++ engineer with 4+ years of commercial experience in telecom systems, high-throughput client–server networking (Qt,
Boost.Asio) and Unreal Engine 5 game development. Focused on performance: reduced drone-link payload size by 72% with
Protocol Buffers, increased server throughput 10x with a thread pool, and raised frame rate from 10 to 60 FPS. Comfortable
owning both architecture and hands-on implementation, and coordinating small teams.
