What I'm looking for

I’m looking for a backend-focused role where I can design microservices and event-driven systems, improve performance with strong testing and code reviews, and collaborate in an Agile team using AWS and Docker to deliver reliable products.

I’m a Software Engineer with 4+ years of experience building scalable backend systems, specializing in Java (Spring Boot) and PHP (Laravel). I design microservices architectures, RESTful APIs, and event-driven systems integrated with RabbitMQ and Redis, with a strong focus on backend performance, resilience, and maintainability.

Across my roles, I’ve shipped features end to end, supported third-party integrations (REST and SOAP), and improved code quality through unit and integration testing (JUnit, Mockito, PHPUnit) plus formal code reviews. I also work confidently with AWS (EC2, S3, CloudWatch) and Docker, and I collaborate in Scrum to deliver reliable software.
