Pankaj Kumar
Full-stack Developer
I build full-stack applications. Passionate about creating projects that make a real-world impact. I focus on clean code and user experience.
Recently interned at 
Traycer, where I worked on the usage dashboard, logs API, and a VS Code-style diff viewer.
Before that, was at 
Dukaan helping ship an AI website generator.
I work with Next.js and Express.js most days, using TypeScript for type safety. I enjoy building things that look good and perform well.
Open to collaborations and opportunities. Feel free to reach out!
