AI/ML ENGINEER — FRESHER — MUMBAI / HYDERABAD

I build AI systems the way a physicist runs an experiment — measured, tested, and shown to work.

Physics graduate, self-taught into AI/ML engineering through five shipped systems — not a stack of course certificates. Each one is deployed, evaluated, and documented the way a lab notebook records a result: what was built, how it was tested, what it proved.

Status: actively interviewing

Who I am

I didn't come up through a CS degree. I studied Physics at the University of Mumbai — where the job isn't to have an opinion, it's to design an experiment, run it, and let the result speak. That habit is the throughline in everything I build now: not "does the demo look good," but "does it hold up when you measure it."

After a year spent exploring direction, I enrolled in a structured Data Science & AI program at the Boston Institute of Analytics in December 2025 — and in parallel, taught myself the rest by shipping. Five end-to-end systems, each one deployed and evaluated, not left in a notebook.

I have no internship on my resume yet. What I have instead is a body of work I can walk anyone through line by line — architecture, failure cases, and the numbers that prove it works.

What I'm looking for

AI/ML Engineer GenAI Engineer Data Scientist Data Analyst

An entry-level role at an analytics-focused or AI-native team — the kind of place where a working system and a clear evaluation matter more than which degree is printed on my resume.

I'm equally interested in roles titled "Data Scientist" or "GenAI Engineer" as I am in "AI/ML Engineer" — the work overlaps more than the titles suggest, and my projects span both the modeling side (fraud detection, feature engineering) and the agentic/LLM side (RAG, tool-calling, multi-agent evaluation).

This site exists to do one thing: let a hiring manager verify, in under three minutes, that I can take an AI system from architecture to a deployed, evaluated result. Not a portfolio of promises — a log of experiments that passed.
