I’m a senior Java full stack developer with 8+ years of experience building and modernizing enterprise, cloud-native applications across banking, healthcare, financial services, telecommunications, and retail. I specialize in secure microservices with Spring Boot, REST APIs, and event-driven architectures using Apache Kafka, and I also build responsive front ends with React.js to deliver fast, reliable user experiences at scale. I’ve delivered measurable outcomes such as improving page and integration performance, increasing throughput during peak loads, and strengthening security with Spring Security, OAuth 2.0, JWT, and RBAC. I enjoy working end-to-end—designing scalable solutions on AWS (EKS, RDS, S3, IAM, CloudWatch), containerizing with Docker/Kubernetes, and automating releases with Jenkins/GitHub Actions—while also leveraging Python for operational automation and validation to keep systems highly available and production-ready.…I’m a senior Java full stack developer with 8+ years of experience building and modernizing enterprise, cloud-native applications across banking, healthcare, financial services, telecommunications, and retail.
