About
I am a hands-on Java Software Engineer with a track record of delivering enterprise backend systems for government, financial, and healthcare domains. I specialize in building and maintaining Java-based REST APIs, working with SQL databases, and supporting production systems used by thousands of users. I have production experience with Spring Boot in enterprise environments and a solid Java foundation that allows me to ramp up quickly.
I’m comfortable across the full software development lifecycle, prioritizing stability, code quality, and collaboration. I’ve delivered secure systems using RBAC, built dashboards with Jasper and Crystal Reports to streamline reporting, and worked with cross-functional teams in Agile/Scrum, leveraging Git, Jenkins, CI/CD, and JIRA to keep software reliable and maintainable.
