You will get clean, scalable code delivered on time — built for real users
Project details
I build scalable, production-ready full-stack web applications using React.js, Next.js, Node.js, Express.js, MongoDB, MySQL, and AWS. With 3+ years of experience, I have delivered 10+ applications serving 1K+ users, including multi-vendor e-commerce platforms, vendor management portals, real-time delivery tracking systems, AI-powered products, dashboards, and payment-enabled applications.
What sets my work apart is the combination of clean, responsive user interfaces and reliable backend architecture. I focus on secure authentication, well-designed REST APIs, database optimization, real-time communication with WebSockets, third-party integrations, and smooth cloud deployment. I have improved application performance by up to 30%, reduced API latency by 20%, and automated workflows by up to 80%.
I prioritize clear communication, maintainable code, practical problem-solving, and delivering solutions that are fast, secure, easy to manage, and aligned with the client’s business goals.

I build scalable MERN/PERN applications end-to-end: responsive React/Next.js frontends, secure Node.js/Express or Python/FastAPI backends, and clean database design in MongoDB or PostgreSQL. I've delivered 10+ production applications supporting 1,000+ active users, cut API latency by up to 20% through query optimization and caching, and built real-time features (WebSockets/Socket) handling 1,000+ concurrent connections for live tracking and notifications.
Recent focus: integrating AI/LLM capabilities into products — RAG pipelines, OpenAI/Groq API integration, prompt engineering, and streaming responses — plus hands-on ML work (fine-tuned BERT and LSTM models for NLP tasks).
Highlighted work: StoreFlaunt (multi-vendor e-commerce platform with live delivery tracking using React, Node.js, MongoDB, WebSockets, Cashfree payments), Featherbazaar (AI-powered blog platform with automated content generation using Next.js, Node.js, AWS EC2), and Sentiment Analysis Pipeline (TF-IDF, LSTM, and fine-tuned BERT on 100K reviews using Python, TensorFlow, HuggingFace).
I also bring hands-on experience with AWS (EC2, S3, Lambda, SQS, SES), Docker, and payment gateway integration (Cashfree), and I've resolved 50+ production issues across live systems — so I write code that's built to run reliably, not just demo well.
B.Tech in Computer Science. Let's talk about what you're building — I respond fast and deliver clean, maintainable code on time.
