About

Professional summary

I am an AI-Powered MERN Stack Developer with over one year of experience building scalable, production-ready full-stack web applications. My core expertise includes React.js, Node.js, Express.js, MongoDB, and RESTful API development.

I build responsive user interfaces and robust backend services with a focus on clean architecture, performance optimization, and maintainable reusable components. I have delivered applications across healthcare, e-commerce, real estate, and interview-preparation domains.

I have hands-on experience integrating AI capabilities using OpenAI API, Gemini API, LangChain, RAG systems, vector embeddings, prompt engineering, AI chatbots, and recommendation engines. I enjoy applying generative AI to practical workflows that improve user experiences and operational efficiency.

My backend experience includes JWT authentication, role-based access control, database design, MongoDB aggregation, payment gateway integration, API integration, and real-time features using Socket.io. I have also worked with Stripe, Razorpay, Firebase, and third-party APIs.

I am comfortable with cloud deployment and development workflows using AWS, Vercel, Netlify, Render, Git, GitHub, CI/CD pipelines, and modern build tools. I use AI-assisted development tools such as GitHub Copilot, Cursor, Claude Code, and ChatGPT for coding, debugging, reviews, and rapid prototyping.

I am passionate about delivering measurable results through optimized full-stack solutions, including faster load times, improved application performance, reduced manual effort, and reliable cross-browser responsive experiences.
