Refactored the RADEC Vision image pipeline from Python to C++, utilizing Boost ASIO, lock-free data structures and multithreading to achieve a 6x throughput increase (15 to 90 FPS). Built an asynchronous telemetry engine in Rust and PostgreSQL to ingest 150k+ daily operational events and expose system bottlenecks. Architected a decoupled MQTT and FastAPI sensor pipeline, processing millions of daily data points from remote IoT devices for structural health monitoring.
