What I'm looking for

I seek full-stack or frontend roles where I can build user-centered web apps, work with modern JS stacks, collaborate cross-functionally, and grow into larger product responsibilities.

I am a results-driven full-stack developer specializing in the MERN stack and Next.js, with hands-on experience building scalable, user-focused web applications and production-ready features that drive business results. I design and deploy end-to-end solutions—authentication, payments, responsive UI, and deployments—using technologies like React, Next.js, Node/Express, and MongoDB.

My projects include an online library platform with subscription payments, e-commerce solutions, an AI-powered browser summarizer, and a secure expense tracker. I collaborate cross-functionally, prioritize deliverables, and leverage tools such as Git, Docker, Vercel, and Netlify to deliver reliable, maintainable products.
