About me

Engineer by craft, builder by nature

A quick look at who I am, what I've been working on and how I like to build.

Hello, I'm Khalid 👋

I'm Muhammad Khalid Chouhan — many people online know me as Khalid Chouhan Gujjar. I'm a Full Stack Developer at TechOn Ventures, building InstaPay — a global fintech platform for international transfers, virtual cards and real-time payments. I currently lead the team behind the InstaPay Agency Panel, working across both frontend and backend: from database design and REST APIs to fast, polished interfaces.

I work remotely with teams anywhere in the world, and I'm currently completing my BSCS at Virtual University while working full-time — which has taught me to be deliberate with my time and ruthless about what actually moves a project forward.

Outside of client work, I build my own products end-to-end — partly to learn, partly because I like seeing an idea become something people actually use. If you value clear communication and steady execution over noise, I'm always open to a good collaboration.
