What I'm looking for

I seek backend roles where I can own secure, well-tested Spring Boot services, work on payments or API-first products, and contribute to reliable architecture and CI/CD practices within collaborative, delivery-focused teams.

I am a Java backend developer with extensive payments and card-processing domain experience, building production-style Spring Boot services with secure REST APIs, strong testing discipline, and end-to-end ownership from analysis to delivery. I have implemented JWT/RBAC security, JPA/Hibernate persistence, PostgreSQL schemas with versioned migrations, Dockerized environments, CI/CD pipelines, and Testcontainers-backed integration tests.

Across roles I delivered customer-facing payment flows, led Way4 platform internalization, and developed a backend-first language-learning product with layered automated tests and 60+ REST paths. I prioritize reliability, clear API design, and maintainable architecture informed by DDD, SOLID principles, and pragmatic automation to keep delivery fast and safe.
