About Tarun Sai Yerragunta

I am a Java Full Stack Developer with 3+ years of experience building and modernizing enterprise systems across government, ERP, and healthcare domains. Currently at NYS Information Technology Services, I work on a tax platform that serves tens of millions of New York residents — modernizing legacy COBOL systems into Java microservices and working on tax underpayment assessment workflows that impact billions in state revenue. My core strength is backend development — designing REST APIs, building ETL pipelines, optimizing databases, and automating CI/CD workflows — while also being comfortable across the full stack with front-end dashboards and cloud deployments. I enjoy working on systems where performance and accuracy genuinely matter. I hold a Master\'s degree in Computer Science from the University at Albany - SUNY and have hands-on experience across Java, Spring Boot, Microservices, SQL, Docker, Kubernetes, and AWS.
