I'm Pankaj Kumar Bijarniya, a full-stack software engineer who loves building elegant, scalable platforms across web, mobile, cloud — and browser extensions.

I've contributed to 25+ real-world projects over 3+ years — from multi-channel logistics and real-time tracking apps to AI-driven edtech platforms and interactive 3D code tools.

I practice Test-Driven Development (TDD) and thoughtful System Design (both HLD & LLD) to ensure maintainable, scalable, and production-ready software.

I care deeply about usability, performance, and clean architecture — crafting tech people rely on every day.
