What I'm looking for

I’m looking for a team where I can build and modernize microservices, focus on performance and reliability, and take ownership as a Team Lead—collaborating closely in Agile/Scrum with QA and DevOps.

I’m a Software Engineer with 2+ year of SWE experience, focused on building highly available microservices, optimizing low latency search algorithms, and driving performance improvements in distributed environments. I enjoy turning complex requirements—like blockchain integrations and secure access—into reliable backend systems.

At Airdrops Factory, I designed and implemented a microservices architecture with Spring Boot, optimizing for distributed environments and ensuring (9 2 %) uptime within blockchain systems. I led performance testing and optimization efforts, improving overall system efficiency by 30%, and I resolved 70+ production issues of critical priority while coordinating and leading 2 developers under pressure.

At the Ministry of Ecology and Natural Resources of the Republic of Azerbaijan, I built authentication and authorization using Spring Security and Keycloak, enabling secure OAuth2/JWT-based access and reducing manual token handling errors by ~80%. I also implemented Kafka-based inter-service communication (contributing to ~40% reduction in response latency under load), standardized deployments with Docker/docker-compose, and centralized observability with Grafana to improve maintainability.
