Shubhainder Singh

Software engineer who ships products

Bangalore, India

I'm Shubhainder. I build software the way it's meant to be built: end to end, in production, owned all the way through. I've taken products from an empty repo to real users: full stack apps, applied AI features, a couple of shipped Chrome extensions, and a Top 5 finish at the Google AI Exchange Hackathon. Right now I'm building Bluey Email, an email platform people actually trust to land in the inbox. I care about the details most people skip: the 200ms, the edge case that only shows up at 2am, the data model you'll thank yourself for a year from now. Off the keyboard I'm on the squash court training the same instinct: read fast, move first, don't flinch. If you're building something that actually matters, we'll get along.

How I Build

I do not have a favourite language. I have a favourite way of thinking about problems. Tools are a means; the job is shipping something that still holds up six months after the demo. Here is where I go deep, and what I reach for when I get there.

Product & Frontend

I obsess over the first 200ms, the ones that decide whether someone stays. Interfaces that feel fast, fail gracefully, and never make the user think.

Backend & Data

APIs that scream in development and stay quiet in production. I would rather get the data model right once than patch around it for a year.

Applied AI

LLM features that survive real users, not just the happy path demo. A Top 5 finish at the Google AI Exchange Hackathon came out of this corner.

Cloud & Delivery

Shipping is a feature. Lambda, EC2 and Route 53 out front, a clean deploy pipeline behind, and two Chrome extensions live in the store.

The stack will change every couple of years. What will not: reading the codebase before rewriting it, knowing what to leave out, and owning what I ship after it goes live.
