Sajin Tamang

I am a full-stack developer focused on building responsive, real-time web applications that solve collaborative and educational problems. I design and implement both frontend interfaces and robust backend services to deliver fast, reliable user experiences.

I built DevChat, a real-time collaborative code editor, implementing WebSockets for instant synchronization, multi-language execution via the Piston API, host-controlled execution, presence tracking, chat, and sharable room management. I also designed the UI using React, Monaco Editor, and Tailwind CSS backed by a Node.js + Express server.

On Edumentor, I developed an AI-powered online learning platform with Node.js/Express backend for authentication, quiz management, progress tracking, and AI feedback; MongoDB stores user data and progress while a React + TypeScript frontend delivers real-time score updates and feedback.

I pursue practical, user-focused engineering: clean interfaces, scalable data models, and reliable real-time systems. I value collaborative environments where I can contribute full-stack expertise and continue improving systems for learning and teamwork.
