About Me

I build scalable web applications and AI-powered systems that solve real-world business problems.

As a Full-Stack Developer specializing in MERN Stack and Next.js, I’ve delivered enterprise dashboards, AI-driven RAG chatbots, and CMS-powered websites handling dynamic and real-time workflows. My work integrates OpenAI/Gemini APIs, Slack, Twilio, and Google APIs, ensuring seamless automation and engagement.

I thrive on end-to-end development from architecture to deployment on Vercel and AWS optimizing APIs, database performance, and user experience. I also bring hands-on experience in legacy system modernization, migrating projects to scalable, maintainable modern stacks.
