## About

I'm a Full Stack Developer with professional experience building web applications using Node\.js, TypeScript, React\.js, and Next\.js, with a strong focus on backend systems, APIs, and real\-time communication\. At Dvika Next\-Gen Tech Solutions, I worked on production applications across the frontend and backend, building REST APIs with Node\.js, TypeScript, Express\.js, and MongoDB, along with React\.js and Next\.js modules\. I also worked on real\-time features using Socket\.IO and WebSockets, including messaging, typing indicators, online presence, and read receipts\. I have hands\-on experience with Redis caching and Redis Pub/Sub, authentication and authorization, MongoDB indexing and query optimization, Docker\-based deployments, and GitHub Actions\. Outside of professional work, I build projects that help me go deeper into backend engineering\. I've worked on a real\-time chat platform using Socket\.IO, Redis Pub/Sub, and MongoDB, as well as an inventory reservation and checkout system using PostgreSQL and Prisma with transaction\-safe reservations, concurrency protection, idempotent checkout workflows, and automated tests\. I'm particularly interested in building reliable APIs, real\-time systems, scalable backend services, and full\-stack applications where performance and correctness matter\.
