Hi, I’m Prince Pal

Backend Engineer & Problem Solver

Passionate about scalable backend systems and AI-driven technologies. I enjoy turning complex ideas into elegant solutions using Go, Node.js, and modern tools.

I’m a self-taught engineer from a small village — building projects that combine creativity, logic, and impact.

Currently open to freelance, collaborations, and full-time opportunities. Let’s connect →
