I build high-load Golang backends for payments, messaging, and public services.

At Tutu Kazakhstan, I optimize a messaging platform handling up to 500,000 SMS, push, and email tasks per day, using Redis queues, delivery retries, monitoring, and clearer error handling. I also built a centralized image service for terabytes of company media, with APIs, CDN delivery, Grafana/Prometheus monitoring, and practical integration documentation.

Previously at OneVision Payments, I launched core payment backend services from the ground up, built anti-fraud checks, and integrated directly with banks and payment providers to expand transaction capacity while reducing reliance on third parties.

I've also delivered regulator-required financial systems processing over 3,000 transactions per minute at Freedom Pay, supported transit payments for more than 100,000 daily passengers, and built B2B verification, traffic-fine payment, and document-generation services at Perezvoni LLC.
