What I'm looking for

I seek backend roles where I can deepen Java/Spring Boot expertise, contribute to API and microservice design, work in collaborative Agile teams, and take ownership of quality and delivery through automation and CI/CD.

I am a Java backend engineer with over three years of experience bridging QA and backend development, building automation frameworks, and ensuring product quality. I have designed microservices with Spring Boot, developed and optimized REST APIs, and worked with relational and NoSQL databases while applying DevOps practices and CI/CD pipelines.

Previously, as a Software Engineer in Test I increased test coverage and reduced regression time by 30% through Selenium and Playwright automation, mentored junior QA engineers, and collaborated closely with DevOps and development teams. I value clean code, thoughtful collaboration, continuous learning, and ownership in diverse, inclusive teams.
