I’m a Java-focused freelance web developer and software engineer with 6+ years of experience building, maintaining, and troubleshooting enterprise web applications. I work across the full stack—using Java, Spring Boot, JavaScript, HTML/CSS, and REST APIs—to deliver reliable solutions that keep business-critical flows running smoothly. I’m comfortable diagnosing production issues end-to-end by tracing problems across UI, APIs, backend services, and databases, then implementing fixes with clear communication and solid engineering practices. From query optimization in SQL/PLSQL/NoSQL to CI/CD-supported deployments on AWS/Docker/Kubernetes, I prioritize dependable performance, security, and timely resolution of defects.
