What I'm looking for

I’m aiming to continue advancing as a back-end developer—leading transformative projects with secure, scalable microservices. I want to stay ahead of emerging trends while collaborating closely with teams to deliver high-quality solutions.

I’m a Senior back-end Java developer with 10+ years of experience delivering JDBC and high-quality Java solutions across banking, insurance, and retail. At Avanade, I design, develop, and implement scalable, secure, and efficient back-end systems for major financial institutions.

My core strengths are building microservices with hexagonal architecture using Java with Spring Boot and Quarkus. I also leverage technologies like Docker, Camunda, PostgreSQL, and Azure DevOps to streamline the development lifecycle and deployment pipeline, while producing REST APIs and reliable service orchestration.

I value collaboration and teamwork because it’s how I help teams deliver transformative results and keep improving professionally. My background also includes Java development with PL/SQL, Apache Camel, and tooling like Jira, Git, and Mockito, plus earlier experience across fullstack and mobile development roles.
