Abror Abduganiev

I’m a Senior Java Backend Engineer with 5+ years of hands-on production experience delivering scalable Spring Boot microservices. I’ve built and evolved services across enterprise consulting, fintech, and high-traffic product environments, with a strong focus on reliable REST API design and data integrity.

Across my roles, I’ve owned backend services end-to-end—from architecture and implementation through testing, code review, and operational readiness. At EPAM Systems, I helped drive modern Java tooling and patterns into legacy code, improving testability and reducing duplicated logic while expanding automated test coverage to cut QA regressions.

In product and fintech settings, I’ve led critical delivery with security and performance in mind. At WAIRER Company, I defined service architecture and data models from scratch, shipped PostgreSQL-backed REST APIs, and implemented authentication, authorization, and audit-logging layers; I also containerized services and deployed to AWS for dev and production.

I’m comfortable operating under audit, transaction-consistency, and regulatory constraints while tuning for throughput and tail latency. From integrating payment gateways and SMS providers with reconciliation/retry/idempotency logic to refactoring shared modules for safe evolution, I focus on building systems that stay maintainable under high-change-rate sprints.
