Agrim Khandelwal

I started writing code because I wanted to know how a URL turns into an APP :)

I had no idea what "software architecture" was. I was just building things, breaking them, and taking whatever freelance gigs I could find to build real stuff for real people…

My first real lesson wasn't React or Node — it was fixing bugs in production after real users found them. Everything I know about auth edge cases, payment webhooks and query performance came from running live products, under real users, not from a course certificate.

It started as building things.
Then it became a way of thinking.
Architecture came later.

// PLACES I'VE SHIPPED AT learned a lot here!

Software Developer at Mittsure Technologies (EdTech) — current
Full-Stack Developer at Churan Chacha (Pansoriya Foods Pvt. Ltd.)
Built & run PrepCUET — a live CUET prep platform, solo, end to end
Freelanced full-stack projects — landing pages to full platforms

Skills, grouped by where they live in the stack.

Everything here has shipped in a real project — no résumé padding, no "familiar with".
