Available to hire
Hi, I’m Vishwa Patel, a software engineer with 4+ years of experience delivering web-based, client/server applications across the full software development life cycle. I specialize in designing scalable backend systems with Java, J2EE, Spring, Hibernate, and microservices, and I enjoy building responsive front-end experiences with React.
I’ve led end-to-end development of secure portals, built RESTful microservices, implemented cloud deployments on AWS, and championed test-driven development with high test coverage. I’m passionate about writing clean, maintainable code, collaborating with cross-functional teams, and continuously learning new technologies to solve real-world business problems.
