Backend Engineer — Node.js · NestJS · TypeScript
I build backend systems for products that handle money and scale: payment integrations, event-driven microservices, PostgreSQL performance work and real-time data pipelines. I work on contract with fintech, marketplace and IoT/retail teams, fully remote.

Payments. Author and maintainer of uz-pay-sdk, a TypeScript SDK that unifies Payme, Click, Uzcard, Humo and Apelsin behind one API — driver-based providers, signed webhooks, idempotency keys and safe retries. Published on npm.
Event-driven backends. NestJS services that talk over RabbitMQ with topic exchanges, dead-letter queues and retry policies instead of tightly coupled HTTP calls.
PostgreSQL performance. Schema design, indexing and query tuning — 40–60% API latency reductions on production endpoints serving 300K+ catalog items.
Real-time and offline-first. WebSocket dashboards for live metrics, logs and alerts, plus bulk event processing and deduplicated offline sync for RFID retail inventory.
