Java Full Stack Developer

Summary

I’m a Java Full Stack Developer with over 7 years of experience building scalable, high-performance web and enterprise applications. I’ve worked extensively across the full SDLC, from analysis to production, and have contributed to major platforms in finance, insurance, and healthcare. My backend expertise centers on Java 8–21, Spring Boot, Hibernate, and microservices architectures. I’m experienced with containerized deployments using Docker and Kubernetes (AKS, EKS, OpenShift), and I’ve built robust CI/CD pipelines using Jenkins, Flux, Bamboo, and more. On the front end, I’m proficient in Angular (2+ to 14), ReactJS, and TypeScript. I have experience building responsive SPAs and reusable UI components. I also bring solid experience with GraphQL, REST, SOAP, and Swagger/OpenAPI. Security is second nature, from OAuth 2.0 and JWT to IAM roles and SSL, and I’ve implemented these across both frontend and backend systems. I’m comfortable across cloud platforms (AWS, Azure, GCP), and have worked with caching (Redis), search (Elasticsearch), and monitoring (Splunk, CloudWatch, Grafana) tools to keep things fast, secure, and reliable. I keep things clean, modular, and testable, using JUnit, Mockito, Cucumber, Selenium, and more. I’m also all about collaboration, Agile delivery, and writing code that makes sense to the person who reads it next.
