Harmanpreet Singh

CEO & Co-founder, Harav Technologies

We brought Harsimran in at Harav Technologies when our app was bleeding users on Android — random crashes, slow cold starts, the usual mess. He didn't just patch things; he pushed back on decisions we'd made early and rewrote the state layer. Crash-free sessions went from 94% to 99.6% in about three weeks. Fast thinker, doesn't sugarcoat things, and writes code the next engineer can actually read.

Ruchika

Software Developer

Worked with Harsimran on the same project for months and he's the kind of engineer you want on your side during a tight sprint. Picks up unfamiliar parts of the codebase fast, reviews PRs properly instead of rubber-stamping them, and is genuinely helpful when you're stuck on something dumb at 11pm. Learnt a lot just pairing with him.

Mandeep Kaur Gill

CEO, SmartNurses Hub

Harsimran built the SmartNurses Hub platform for us end to end — from the information architecture to the member flows and the training-resource delivery. What stood out was how much he cared about the product, not just the code. He flagged things I hadn't even thought about, pushed back where it mattered, and delivered on time. I've recommended him twice since.

Daniel Carter

Product Manager

Worked with Harsimran on a product I was managing end-to-end, and he's the rare engineer who actually engages with the product questions instead of just closing tickets. He'd push back on requirements that didn't make sense, suggest simpler alternatives, and ship on time anyway. Made my job as PM noticeably easier — fewer clarification loops, fewer surprises in QA.

James Anderson

Engineering Lead

Brought Harsimran onto a project mid-stream when we were behind schedule and the codebase wasn't in great shape. Within a week he'd mapped out what was salvageable and what needed to go, and within a month we were back on track. Straightforward to work with, no ego in code review, and clearly thinks about the team's velocity and not just his own tickets.

Vipin Saini

Software Engineer

Shared an office and a codebase with Harsimran for long enough to know how he works. He's the engineer who reads the code before opinionating on it — two quiet days, then a migration plan that actually makes sense. Comfortable saying 'I don't know yet, let me check,' which I respect more than people who pretend they do.

Meharpreet Singh

Mobile Developer

Worked with Harsimran on a couple of mobile projects and he's one of those engineers who makes the rest of the team better just by being around. Reviews are thorough, debugging sessions are fast, and he'll drop what he's doing to help you unblock. Also the only person I know who actually writes commit messages worth reading.
