Full Stack Developer | Node.js, Typescript, PostgreSQL, MongoDB, Redis, React.js, Next.js | Real Time Ststems and Scalable REST APIs

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.
