About

Java Full Stack / React.js Developer with around 5 years of experience building scalable, high-performance web applications across Healthcare, Banking, and Insurance domains. I work across the full stack - designing REST APIs and Microservices with Java, Spring Boot, Spring MVC, Spring Data JPA, and Hibernate on the backend, and building modern, responsive UIs with React.js, JavaScript (ES6+), Redux Toolkit, HTML5, CSS3, and SCSS on the frontend - with MongoDB and SQL for data persistence. Throughout my career, I've developed reusable React.js components and Java backend services, integrated frontend applications with Spring Boot Microservices, optimized application performance, and resolved production issues. My work spans patient management systems, clinical operations and reporting (Healthcare), secure customer and account APIs and CASA functionality (Banking), and insurance platforms with dynamic reporting and document workflows. I collaborate closely with UX/UI designers, backend engineers, QA teams, and business stakeholders in Agile/Scrum environments, and I'm comfortable owning a feature end-to-end - from API design through UI delivery. I also use AI-assisted development tools (GitHub Copilot, ChatGPT, Windsurf, Devin) to speed up development and improve code quality. I'm currently open to opportunities where I can apply my full-stack Java + React expertise to impactful products alongside strong engineering teams.
