When AI writes better code.

The future of software development revolves around validation. Not writing code.

I’ve been coding since eighth grade. Now I’m building an IDE that gives an interface for parallely validating AI-generated code.

More time
engineering the result.

“If AI is writing the code, I want to spend my time validating the results.”

As AI Agents entered my workflow, I realised I had to wait for every agent to finish before I could proceed to validate. And prompt next.

I’m building Headwig, an IDE built around validation: a place to evaluate results, compare approaches, and evaluate performance in isolation while agents work in parallel.

The Beginning

A story that started in
Purnea, Bihar, India.

Not every founder's journey begins in a city with a startup ecosystem. Sometimes it begins in a quiet town, with curiosity, ambition, and the feeling that the world is larger than what surrounds you.

Learning to Build
"I am not a product of my circumstances.
I am a product of my decisions." Stephen R. Covey

Growing up in Purnea, Bihar, ambition had to be self-generated. There was no startup culture, no network of mentors, no visible path. But there was a particular kind of drive that small towns give you, the one that asks what's possible beyond the horizon.

That drive carried me to IIT Bombay, where I didn't just study, I built. Products used by thousands. Communities that shaped campus life. Systems that outlasted my time there. And then to Hilti Group, where I touched something different: the intersection of industrial hardware, large-scale software, and real-world manufacturing.

Today, I’m building Headwig alongside my work at Hilti. Years of building software have led me to a new question: when AI writes the code, how should we spend our time engineering the result?

Earlier Chapter · Co-Founder

Faoud,
Factory on Cloud.

Before Tamaso, I co-founded Faoud to bring greater visibility and structure to Indian manufacturing. We built workflows for factory discovery, bid comparison, production tracking, quality control, and execution.

Working closely with factories made one thing clear: organisations do not only need more software. They need an intelligence system that understands how their data, people, machines, and processes fit together. That learning became part of the foundation for Tamaso.

Tamaso.

Tamaso explored how fragmented operational data could become a contextual model of how an organisation worked, helping people understand their operations and make better decisions.

We visited factories, spoke with managers and operators, and mapped how information moved between people, machines, and existing systems. We designed prototypes for a mushroom factory and Mypol.

Industrial Software

Where hardware
meets the cloud.

At Hilti Group, I work as a software engineer on modeling software used in large-scale MEP and structural applications, touching systems that operate at the intersection of 3D modeling, industrial hardware, and real construction environments.

An observation visit to Switzerland, including the Lonza facility, grounded this work in physical reality. It changed how I think about software.

Switzerland Exposure

From Code to Construction

Visited the Lonza facility in Switzerland, observing how software-designed systems translate to hardware installations in large industrial environments. This grounded my understanding of software's physical stakes.

IIT Bombay, Builder Years

Products built
for real
communities.

At IIT Bombay, I didn't wait for a startup, I built one within the campus itself. Products that touched thousands of students. Communities that reshaped how people talked to each other. Systems that had to work at scale, from day one.

Entrepreneurial Experiment

A pH Scale,
the agency
that started
everything.

In my final year at IIT Bombay, I started A pH Scale, a small storytelling and marketing agency created to understand how products communicate. Every brand has a story that hasn't been told well yet. We told it.


It was an experiment in business, creativity, and execution, proof that a technical person can also understand what moves people. Design, writing, strategy, all of it built from scratch.

"There is no greater agony than bearing
an untold story inside you." Maya Angelou

Filmmaking taught me what no engineering course could: how to shape attention, how to create meaning from sequence, and how to make someone care about something abstract. I won at Inter-IIT film competitions and received the Xiaomi Ad Award, recognition that storytelling, when done with precision, is indistinguishable from craft.


This isn't a hobby that runs parallel to my technical work. It is the lens through which I build products, with a sense of narrative, user experience as story, and interfaces as conversations.

The Journey

Every place
changed the work.

The Beginning

Purnea, Bihar

Grew up in Purnea, a small city in Bihar where ambition had to be self-made. No startup culture, no visible shortcuts. Just curiosity and a drive to understand how the world worked, and how to build in it. Sold servives to build homepage to get funds for idea of edtech. It was named MagicalStud. My personal gmail today is harshatmagicalstud@gmail.com.

Got introduced to IITs by my guru in hometown, Batul Da Sir. He used to say

"You should always try to observe
physics,
it's not to learn, it's to see." Batul Da Sir

Entrance & Arrival

IIT Bombay

Joined IIT Bombay for a Chemical Engineering major and a minor in Computer Science, and immediately started building. The campus became a laboratory for products, communities, and creative work. A lot of what I know about building for users was shaped here.

Builder Years

InstiApp · DevCom · Mess-I · NewBee

Four years of shipping. Products used by 20,000+ students. Communities that shaped campus discourse. Systems that handled real-world constraints. Every project was a lesson in scope, scale, and speed.

Creative Chapter

Films · A pH Scale · Xiaomi Award

Ran a marketing agency, made films that won at Inter-IIT, won an ad award from Xiaomi. Discovered that building things and telling stories about them are not separate disciplines, they are the same skill, expressed differently.

Industry Exposure

Hilti Group

Joined Hilti as an engineer working on 3D modeling software for MEP systems. Built in Three.js, integrated with Navisworks, Revit, and RSTAB. Understood industrial software from the inside.

Global Perspective

Switzerland & France, Lonza & Beyond

Observation visit to Switzerland, including the Lonza facility. Saw how software-designed modular systems translate into physical hardware installations. The gap between digital model and factory floor became viscerally clear.

Building in Manufacturing

Faoud, Factory on Cloud

Co-founded Faoud and built manufacturing workflows for factory discovery, bid comparison, production visibility, quality, and execution. The experience revealed the deeper need for a connected intelligence layer across physical operations.

Prototype Work

Tamaso

Explored an intelligence layer for physical operations through factory visits and conversations with managers and operators. We designed prototypes for a mushroom factory and Mypol.

A Parting Thought

The best systems are built by people who remember
where they came from, and refuse
to be limited by it.

I came from Purnea. I build for the world. Everything between those two facts is the story I’m still writing. Today, I’m exploring how software engineers can turn the time AI saves into better results.
