Himujjal Upadhyaya
Turning code into happiness one line at a time. Tinkerer. Product Engineer. I thrive where speed matters and the rules are made up.
// what I do
How I can help your startup
Build
From idea to shipped product. Apps, platforms, tools — I take your vision and turn it into something people can use.
Fix
Broken, slow, or falling apart? I find the problem and make it work. Performance, architecture, reliability.
Think
The hard problems before code. Architecture, infrastructure, technical strategy. Decisions that save months.
// how I work
From conversation to shipped product
01. Talk
We figure out what you need. Not what you think you need — what the problem demands.
02. Plan
Architecture, tech choices, timeline. The boring stuff that prevents 3am disasters.
03. Build
Fast, clean, iterative. You see progress every week, not every quarter.
04. Ship
It's live. It works. You have something real to show people.

Things I'm thinking about
Books That Shaped My Thinking
A reading list that reveals how a polymath engineer thinks. JavaScript30, Crafting Interpreters, Andrew Ng, and the Gita.
From Mathematics to Machines
How an M.Sc. in Mathematics became a tech consultant in the age of AI — and why gradient descent beats prompt engineering.
Projects from Scratch
BLE navigation, offline-first sync, Whisper transcription, the Ekam language — projects that taught me the full stack.
The DIY Consultant
Most consultants give you a deck. I give you a working prototype. The DIY philosophy behind better tech consulting.
