I'm Hitanshu Jariwala, a developer who cares about the details
Building things that work. Writing code that lasts.
I started with small React apps, learning by breaking them. What kept pulling me deeper was everything behind the interface: why a query got slow, how to make search understand a question instead of matching words, what happens when two people type at once. Eleven projects later, that's still where the work gets interesting.
Remove a step, don't add a screen
Most of what I've built started as something I was tired of repeating - auth boilerplate, four tabs open to run one shop, folders pretending to be search. The win is usually taking work away, not adding features.
Put a number on it
Sub-100ms message delivery. Profile search under a second. Doc lookup cut by 10×. I'd rather measure the thing than call it fast, because "fast enough" gets decided by the user otherwise.
Dependencies come last
Some of these run on plain React state with nothing else added. A package has to earn its bundle size, its upgrade path and the day it breaks - the ones you skip are the ones that never do.
What I reach for
Grouped by the problem it solves rather than by popularity. Everything here has shipped something.

Where I've been
Formal education on one side, the things I'm proudest of on the other.
2025Achievement1st place - Odoo × Charusat Hackathon
Charusat University
Built and demoed a working product against the clock, judged on both engineering and the problem it actually solved.
