What I'm looking for

I’m looking for a backend role where I can own microservices end to end—designing REST APIs, integrating distributed systems, improving data performance, and strengthening reliability with strong tests and CI/CD—ideally in a team that values clean architecture.

I’m a Java Backend Developer with 3+ years of commercial experience building enterprise, microservice-based systems. I develop and enhance microservices with Java 17 and Spring Boot, design REST APIs, and implement service-to-service integrations using Spring Cloud and OpenFeign.

I focus on clean architecture and reliable delivery—implementing business logic with Hexagonal Architecture principles, writing integration tests with Testcontainers, and supporting CI/CD with Docker and GitLab CI. I’ve optimized critical PostgreSQL and Oracle SQL queries (up to 50%), implemented Redis caching for frequently accessed data, and delivered features like transactional Excel import with validation and rollbacks.
