Maahir Garg

About Maahir Garg. The longer version.

I'm Maahir. I'm finishing a Computer Science and Quantitative Finance degree at NUS, and I spend most of my week at AICET trying to catch cheating in coding assessments without accusing someone who didn't cheat. The honest headline from that work isn't a nice accuracy number. A model that looked promising turned out to be statistically indistinguishable from chance once I ran the right test, and a plain lookup of which question it was beat it anyway. That's a confound, not a detector. I built the tooling that surfaced it, and I'd rather have found it than shipped it.

Before that I was at GIC, building AI tooling for an eleven-person team in a classified-data environment, the kind of place where you can't just point Copilot at a problem. The part I cared about most was the guardrails: checks on every action an agent takes, so nobody downstream has to trust it blindly. A separate pipeline turned hunting for audit evidence across Snowflake and SharePoint into something close to instant.

In the second half of 2025 I worked at Interactive 3D Lab, in collaboration with Apple, on hand and eye tracking for stroke rehabilitation. I built the visionOS side, the spatial interface and real-time tracking, plus the iPhone companion app. It was tested with real clinicians and real patients, which is the part I'm most careful about describing properly. A paper is in preparation and a patent application is in progress.

I also teach. This semester I'm a TA for CS3230, the algorithms course I took as a student, and CS3263, Foundations of AI. Marking algorithm proofs with a red pen is where this site's red pen comes from. I'm also a Residential Assistant at Prince George's Park, and this September I built and ran PGPals, the platform for our residence's Emerald Challenge. Ninety-six teams played, and when it closed there was nothing left waiting in the review queue.

Away from a keyboard: a camera goes most places with me, I play blitz chess faster than I should, badminton and drums fill the rest of the week, and I have strong opinions about Formula 1 pit-stop calls made from my couch.

Routes

Singapore is home, but I've crossed enough of South and Southeast Asia to have opinions about airport lounges.
