What I'm looking for

I seek backend engineering roles where I can build scalable microservices and enterprise systems, collaborate with cross-functional teams, and continue learning in a growth-oriented, English-speaking environment.

I am a Java backend developer with hands-on experience building ERP and microservices systems using the Spring ecosystem; I prioritize performance, maintainability, and clear collaboration with cross-functional and international teams. I improved framework reusability with custom JSF components, optimized database access to remove N+1 queries, and implemented DTO-based reads, server-side pagination, and background workers to speed APIs.

I've delivered RESTful APIs, unit-tested code with JUnit, and contributed to B2B microservices using Spring Cloud and Axon for CQRS and Saga patterns. I communicate effectively in English with stakeholders and clients, and I am pursuing a Bachelor of Software Engineering with a strong GPA while seeking opportunities to deepen my production-level backend engineering experience.
