Senior Backend Engineer

Worked on Uzum Nasiya, a BNPL fintech platform, as part of a 15-developer on-site team. Built a Go reconciliation engine that validates generated business reports against accounting figures across millions of rows using streaming iteration, bounded worker pools, goroutines, channels, context, and errgroup. Designed concurrency-safe financial transaction flows using row-level locking, saga patterns, and double-spend prevention.

Established Go testing practices with table-driven tests, testify, gomock, testcontainers-go integration tests, race detection, and golangci-lint in CI, increasing coverage to 93%. Implemented Prometheus instrumentation and Grafana RED dashboards and alerts. Optimized Laravel APIs through Octane and Swoole, Kubernetes graceful-drain configuration, and worker tuning, reducing API latency from 2–3 seconds to about 50 ms. Also optimized million-row report exports, Dockerized a legacy application, investigated production failures, and mentored junior developers.

Worked remotely on e-commerce platforms, web services, mobile APIs, chatbots, and high-traffic products including chitai-gorod.ru, eapteka.ru, tv3.ru, dostaevsky.ru, rusklimat.ru, and gazprom-media.com. Built a microservice capable of generating one million unique promotional codes in one operation, reducing execution time from 17 seconds to 4–5 seconds.

Delivered configurable promotion APIs for non-technical users, including birthday, order-value, product-count, bundle, and percentage-discount mechanics. Developed GraphQL APIs, restructured services with Repository and Dependency Injection patterns, documented microservices in Confluence, created high-traffic ordering endpoints and third-party integrations, and delivered backend APIs, webhooks, frontend pages, and animations for an online pharmacy project.

Bachelor of Science in Engineering in Computer Science, completed in May 2024. Participated as a GDG organizer in 2020, supporting DevFest, coding contests, Android workshops, and hackathons.
