// about me

Code is craft.
I take it seriously.

I'm Dhirendra Kumar Rana, a full-stack developer with 5+ years building web applications — from early-stage startups to scaling products used by thousands of users daily.

I care deeply about developer experience, performance, and the tiny details that make a product feel polished. When I'm not building, I'm writing about the things I've learned.
