Human First

I Build. The Future of Intelligence

01 / Origin Story

It began, as most dangerous things do, with curiosity.

Not the polite kind. Not the kind that asks questions and waits for answers.
No, this was the kind that unscrews the back panel just to see what happens.

As a child, I didn't play with toys. I interrogated them.
Every gear was a suspect. Every wire had a secret.
And I was determined to expose them all.

There was a sack in my room.
Not for clothes. Not for books.
For remains.

The broken ones. The ones I couldn't put back together.
It filled up slowly… then suddenly, all at once.

One day, my mother looked at it, then at me, and said:
"Curiosity is good. But you should also learn how to fix what you break."

Somewhere along the way, breaking things stopped being enough.

I started chasing something deeper—first principles.
Because breaking is easy; building is where the resistance lives.

Around class 9 or 10, my ambition took a dramatic turn.
From dismantling toys to… fixing society.

Yes, I was that kid.

I wanted to become a civil servant.
Serving the country. Changing systems. Leaving a mark.

I started preparing seriously. From class 8.
(In hindsight, slightly intense for someone still losing socks regularly.)

And then life intervened.

After my 10th boards, something shifted in my family.
Plans that once felt inevitable… became optional.

I didn't sit for JEE.
I wanted to study Physics.

But in India, dreams negotiate with practicality.

So I chose a diploma.
Not because I wanted to—
but because sometimes, survival rewrites ambition.

In college, I met something familiar.

Code.

Not love at first sight. More like recognition.

When I wrote my first working program, something clicked:
"Oh. I can build things now."

There was just one problem.

I didn't have a computer.

So I learned programming… on a broken phone.

A Samsung J7, barely holding itself together.
Through an app called Decode.

C. Python. Small screen. Big persistence.

Then I joined L&T.

Two months in, my manager said:
"Learn programming."

I said, "I know some."

Two days later, I was doing automation.

That's when the bug returned.

Not the error kind.
The itch.

So I learned more.
Java. JavaScript. HTML. CSS. SQL.

No roadmap. No plan. Just curiosity with Wi-Fi.

Then I discovered Machine Learning.

And honestly… it felt like magic.

But reality checked in again.

To grow in India, a degree isn't optional.

So I found a program from IIT Madras.
A 4-year degree. Equivalent to B.Tech.
And I could do it without quitting my job.

So I joined.

Because sometimes, you don't choose the perfect path.
You build one that works.

Somewhere in all this—
automation, data, ML models, GenAI—

I found myself constantly excited… and slightly terrified.

Because every few days, something new drops.
And a voice whispers:
"This might replace you."

(Thanks, Claude.)

But that curiosity from childhood never left.
It just evolved.

Today, I don't break systems to understand them.
I build systems to redefine them.

I don't just study systems anymore.
I write the rules.
