What I'm looking for

I'm looking to build scalable, user-centric web applications and backend systems, especially products involving e-commerce, AI-powered features, real-time services, payments, and production-ready architecture.

I've built production e-commerce, ERP, and academic management platforms for SM Technology, ITCommerz Software Solution, MR. Healer, and Rabindra University. My work includes REST APIs, role-based systems, real-time communication, payment integrations, logistics automation, and library workflows with QR verification and automated fines.

I work across Next.js, React, Node.js, Express, Prisma, PostgreSQL, Docker, AWS, and Cloudflare. I also build RAG-powered applications with vector databases and focus on performance, accessibility, scalable architecture, and user-centric experiences.
