Backend & AI Engineer · Python · Voice AI · Indore, India

I build production AI voice-agent systems — FastAPI / PostgreSQL backends that orchestrate telephony and LLMs to run autonomous phone calls, wired into 15+ third-party CRM, calendar, payment, and email APIs. 7+ years shipping software end-to-end.

Mostly, I just like figuring out how things work — then making them work better.

About

I'm a software engineer in Indore, India — though “engineer” undersells the part I actually love: figuring out how something works, then making it better. I started out building mobile apps, got curious about what powered them, and followed that curiosity all the way down to the backend.

That's how I ended up building a multi-tenant AI voice-agent SaaS — a FastAPI / PostgreSQL backend that orchestrates telephony and LLMs to make and receive real phone calls, wired into 15+ third-party APIs across CRM, calendar, payments, and email, on AWS. The hard problems — call orchestration, voicemail detection, keeping a dozen integrations honest — are the ones I enjoy most.

Seven years in, I've learned I do my best work when I care about doing it right, not about who's watching. I still learn the same way I started: by building the next thing a little better than the last.

The best work doesn't need an audience. I'd rather build something that quietly works than chase something that loudly impresses.
