What I'm looking for

I'm looking to build and own high-performance Go systems for complex logistics, transportation, or e-commerce products, contributing through system design, performance engineering, production ownership, and technical leadership in a remote or hybrid role.

At X5 Tech, I own architecture and technical initiatives for a vehicle-routing platform designed to scale to 200 distribution centers and 30,000 stores. I redesigned its PostgreSQL-to-ClickHouse CDC pipeline, moving nine reports across 30–50M-row tables from roughly 20 minutes to 15 seconds.

I've built Go services for transportation planning, route calculation, geographic clustering, billing, request tracking, and real-time e-commerce recommendations. At ITECO, I improved route calculation speed by 40% and helped reduce failed deliveries by 17% through more accurate delivery-slot estimation.

At Retail Rocket, I built microservices and APIs for personalized product recommendations, cutting median API latency from 180 ms to 90 ms and reducing new-model rollout time from three days to six hours.

I enjoy owning production systems end to end: designing distributed architecture, building CDC and messaging pipelines, running load tests, and improving performance. I've also acted as a team lead, coordinating engineers, technical decisions, estimates, incident response, and backend interviews.
