What I'm looking for

I seek backend roles where I can design scalable microservices, improve reliability with strong testing and standards, collaborate with customers, and grow into technical leadership.

I am a Senior Java backend developer with extensive experience building and maintaining large-scale enterprise systems for automotive, healthcare, travel, finance and logistics clients.

I design and implement backend microservices, data access layers and integration solutions using modern Java (8–21), Spring Boot, OpenAPI and messaging platforms such as Kafka. I focus on performance, test coverage and robust API design.

I have delivered projects involving PostgreSQL, MySQL, Oracle, MongoDB, Redis, AWS and Azure, and introduced unified coding standards, OpenAPI schemas and automated tests to improve reliability and developer productivity.

I communicate directly with customers, perform code reviews, estimate and plan work, and consistently contribute to resolving technical debt while maintaining high engineering quality.
