I build low-latency Go infrastructure and trading systems, most recently connecting infrastructure and trading teams at a high-frequency trading fund. I write exchange connectors, rate-limit-aware scheduling, market-data pipelines, and monitoring that improve reliability under production load.

My connector and feed-health work reduced HTTP 429 responses by 78%, cut unexpected reconnects and restarts by 50–65%, and improved p99 latency stability by 25–40% during peak bursts. I also implemented adverse-selection detection and a markout calculation pipeline for trading metrics.

Previously at Nebius, I built experimental proactive work stealing, deployment controls, and a gRPC dynamic resource-delivery library that reduced polling overhead and delivery time by over 60% with approximately 5 ms p99.9 latency. At Yandex Search Core Infrastructure, I eliminated trace-write data loss during spikes, accelerated archive operations by more than 2x, and delivered a 15x+ image-preprocessing optimization.

I enjoy concurrency, distributed systems, systems performance, and solving difficult production problems close to the hardware and network.
