Hi, I'm Tanya.

I'm passionate about product and technology at the intersection of data-driven decision making. I build products that serve real people, backed by research, and grounded in cognitive science.

I'm a junior at UC Berkeley studying Cognitive Science + Data Science (GPA 3.74). I've worked across the US and India, from enterprise SaaS to clinical settings.

Outside work I'm an athlete and adventurer. I founded a table tennis club from scratch, grew it to 74 members, and ran our first inter-college tournament.

Recently certified as a Six Sigma Yellow Belt.

Problem

Navigation apps don't account for accessibility. Wheelchair users face broken sidewalks and missing curb cuts.

Solution

AI route scoring using crowdsourced data and computer vision. User research with mobility-impaired communities.

Impact

  • Block-by-block infrastructure quality scoring
  • ~3,000+ estimated users across campus pilots

Problem

Podcasts are locked to their original language. Existing translation isn't built for audio-first real-time consumption.

Solution

Real-time translation layer using NLP transcription, neural MT, and voice synthesis. Latency-aware mode switching. Full PRD for ML team.

Impact

  • 4+ target languages, latency-adaptive UX
  • ~5,000+ potential multilingual listeners

Problem

Patients with neurological conditions can't self-monitor speech deterioration between infrequent visits.

Solution

UX research with affected patients, full PRD with adaptive UI states based on detected fatigue. Figma wireframes for clinical review.

Impact

  • Adaptive interface, not one-size-fits-all
  • Full dev handoff completed
