I build high-load Node.js microservices, APIs, and event-driven backend platforms.

I've built and modernized high-load backend systems across fuel retail, adtech, gaming, and automotive for PAR Retail, SkywindGroup, Playson, Intellias, and Luxoft.

At PAR Retail, I develop partner-facing APIs and server-side logic for fuel-retail and loyalty integrations. I also designed an AI-assisted engineering workflow connecting Claude Code, Jira, and GitHub to streamline delivery from ticket analysis through code review.

At SkywindGroup, I built third-party integrations and a ClickHouse analytics solution that offloaded heavy reporting queries from PostgreSQL. I improved observability with metric-based alerts and log monitoring, while supporting code review, onboarding automation, and release-note generation.

Previously, I helped Playson decompose a legacy C++ monolith into Node.js microservices and built migration and validation tooling for a safe rollout. Across automotive projects at Intellias and Luxoft, I've delivered embedded and routing software, supported releases and customer integrations, and mentored junior engineers.
