Udhaar Tracker

Inspiration

Talk about your dad's diamond trading business and how you've seen firsthand how small business owners in India still track customer credit on paper. Mention that shopkeepers extending informal credit ("udhaar") is a real, widespread habit with no simple digital tool built for it.

What it does

Briefly describe the core loop — add customers, log credit/payments, see total dues on a dashboard, generate AI-drafted Hinglish reminder messages for overdue customers.

How we built it

Mention React Native + Expo + TypeScript, AsyncStorage for local-first data (no backend needed), and that you built it end-to-end with Codex — from scaffolding through the data layer, screens, and the GPT-5.6 reminder integration

Challenges we ran into

Getting Expo Go's SDK version to match your project's SDK during device testing A bug you caught where customers who'd never made a payment were getting an inaccurate reminder message — and how you directed Codex to fix it Hitting OpenAI API quota limits and designing a graceful fallback so the app stays fully functional even without live API access

Accomplishments that we're proud of

What we learned

Something genuine — e.g., how much of mobile dev is actually environment/tooling debugging vs. writing code, or what you learned about designing AI features with graceful degradation.
