About Me

I'm a Backend Software Engineer with 5+ years of experience across enterprise and platform environments in Australia, currently at Team Internet, where I design, build and operate services using Java, Spring Boot and Go.

I focus on owning services end-to-end, from architecture through production support, and I'm comfortable reviewing code and providing technical guidance within Agile teams. I enjoy resolving critical incidents under pressure, modernizing legacy systems, and building reliable CI/CD and automated testing practices.

Day to day, I work primarily with Java, Spring Boot, Go, PostgreSQL/MySQL, Docker and AWS, alongside testing tools like JUnit, Mockito and Cucumber. I've also worked with Spring Security/JWT-based authentication, Kafka, and enterprise integrations earlier in my career, and use AI-assisted tools (GitHub Copilot, Cursor, Claude) as part of my daily workflow.
