What I'm looking for

I’m looking for a backend role in Agile teams where I can build and scale microservices, own REST API development, and improve reliability with high test coverage, clean code, and CI/CD—using AWS automation to ship quickly.

I’m a Backend Developer with 4 years of experience building scalable microservice architectures using Java, Spring Boot, and Kotlin. I enjoy designing REST APIs and delivering backend services that are secure, compliant, and maintainable.

At ilaBank, I contribute in a 12-person international team to develop and maintain scalable core-banking services across 100+ microservices. I work on AWS-based automation and data integration solutions using Glue Jobs, Lambda functions, and Python scripts, while collaborating with solution architects to refine designs to business requirements.

I’ve also built secure and scalable backend APIs in Spring Boot, integrating third-party social media APIs and applying DDD principles. My work included Redis, SonarQube, AWS S3, and Keycloak, and I was promoted to mid-level developer in 7 months due to consistent, high-quality contributions.

Earlier, I supported backend feature development as an intern using Kotlin and Spring Boot in Scrum and Kanban teams, and I built observability components with the ELK Stack. I’m especially driven by quality—clean code, high test coverage, and resolving defects from regression testing—so teams can move fast without sacrificing reliability.
