I have extensive experience in MERN (MongoDB, Express.js, React, Node.js) Web Application Development, building scalable, high-performance applications. I specialize in designing RESTful & GraphQL APIs, state management (Redux, Context API), authentication (JWT, OAuth, Firebase), and third-party integrations (Stripe, Twilio, AWS S3). I optimize performance with SSR (Next.js), caching (Redis), and database indexing, ensuring seamless user experiences. Leveraging microservices, Docker, Kubernetes, and CI/CD pipelines, I enable efficient cloud deployment (AWS, GCP). Security is a priority, implementing data encryption, role-based access, and OWASP compliance. My expertise spans real-time applications (WebSockets), PWA development, and UI/UX enhancements, delivering robust, scalable, and secure web solutions for diverse industries.
