What I'm looking for

I’m looking for a team where I can build scalable web and mobile products, improve code quality, and ship production-ready features—while also applying my experience in AI model evaluation and clean PR workflows.

I’m a Full-Stack Developer focused on delivering high-performance, production-ready applications with clean, maintainable code. I build scalable web and mobile experiences using React, Next.js, React Native, and Node.js, with a strong emphasis on architecture, code quality, and smooth user experiences.

Recently, I’ve worked as an AI Trainer & PR writter—training and evaluating AI outputs by validating generated code against real development standards, identifying architectural weaknesses, and improving pull requests for clarity and production readiness. Earlier, I architected a scalable multi-dashboard platform with role-based UIs and REST APIs, and I developed a production-grade eCommerce mobile app with React Native (Expo), Firebase authentication, push notifications, and real-time one-to-one chat.
