What I'm looking for

I'm looking to build and stabilize high-load backend products in fintech, banking, or enterprise environments, and I'm open to relocation and business travel.

I've built backend products at AO Paynet, AO Anor Bank, AxonLogic, and EPAM Uzbekistan, supporting investments, BNPL, railway ticketing, and internal planning systems. At Paynet, I develop investment services for buying and selling gold, cryptocurrencies, precious metals, and other assets, including real-time portfolio analytics.

At Anor Bank, I owned key installment-card flows from issuing and activation through repayments and history. I resolved a production OutOfMemoryError by replacing an unbounded cache with size-bounded, TTL-based Caffeine caching, and improved installment-history performance through Redis caching, database indexes, pagination, and streaming.

I've also cut a railway project's third-party API costs by about 50%, built authorization, notification, statistics, and REST services, and work hands-on with Java, Spring Boot, WebFlux, Kafka, Redis, PostgreSQL, Docker, Kubernetes, and CI/CD.
