What I'm looking for

I’m looking for a role where I can build scalable React/Next.js web apps, ship full-stack Node.js + MongoDB features, and contribute to AI-powered RAG workflows—learning fast, solving real product problems, and delivering clean, maintainable systems.

I’m a frontend-focused Software Developer with strong experience building scalable web applications using React, Next.js, and modern JavaScript frameworks. I also develop full-stack systems with Node.js and MongoDB, and I’m currently building AI-powered applications using Retrieval-Augmented Generation (RAG) workflows.

I enjoy turning real-world problems into products with strong problem-solving and scalable system thinking. In my projects, I built an AI-powered exam preparation platform (ExamHell) using retrieval-based LLM workflows, REST-integrated backend APIs, and scalable Next.js/Tailwind frontend architecture; I also developed a full-stack job application tracker with OAuth-based authentication, and an event management platform with responsive UI components and MongoDB-backed APIs.
