Shortening the distance between thinking, building, testing, and learning.

01 About
I turn data into products people actually use. First-gen student. Cognitive scientist. I let the numbers tell me what to build, then I build it until it works for everyone.

I study cognitive science and data science at UC Berkeley because good products start with understanding people and end with data-driven decisions. I've shipped an AI diabetes platform backed by 10K+ glucose readings for my twin sister's family, a marketplace that kept 127 items out of landfills, and a lyric engine that makes non-English music actually make sense.

I care a lot about accessibility and using data to surface insights for people who usually get left out. That's what led me to building gesture-based games for kids with motor disabilities at a clinic in Mumbai, and what drives most of what I make.

Curb: Student Marketplace

Founder / Builder

Problem: US colleges generate 12.1M tons of move-out waste every year. Students throw away furniture that incoming students buy brand new three months later.

What I built: A hyperlocal peer-to-peer marketplace. List it, match it, hand it off within the 72-hour move-out window.

TAN-1: Predictive Diabetes Platform

Founder / Product Lead

Problem: Families facing a new Type 1 diagnosis juggle glucose readings, carb math, and emergencies across disconnected tools.

What I built: An AI glucose risk engine that turns CGM noise into plain-English caregiver alerts. Started after my twin sister's diagnosis.

LyricSync: Cultural Context Engine

Founder / Builder

Problem: 128M people watched Bad Bunny's Super Bowl halftime. Google Translate gave them "Uncle asked me" for "Titi Me Preguntó." The music hits. The meaning doesn't.

What I built: A Spotify-connected lyric sync engine with contextual translations. Poetry stays poetry. Slang stays slang.

AccessibilityEdTechComputer Vision

NeuroLearner: Gesture Platformer

Product UX Intern · Therapy Tales Clinic

Problem: Kids with motor and cognitive disabilities were locked out of learning games built for able-bodied play.

What I built: OpenCV/MediaPipe hand-gesture tracking for an adaptive learning game. Designed with clinicians in a Mumbai speech clinic.
