The problem

Starting from my own need to track spending, I wanted to replace the tedium of manual expense logging with something that pulls clean, categorized insights straight from my bank notification emails.

What I built

A Tailwind front end on a Supabase backend (PostgreSQL with row-level security, plus edge functions). A Gmail IMAP edge function parses BCA transaction emails, deduplicates them, and imports them with rule-based auto-categorization. I then packaged the web app for Android using Capacitor.

Impact & what I learned

Manual expense logging became an automated flow that turns raw bank notification emails into categorized, visualized financial insights. Along the way I picked up serverless edge functions, secure data design with row-level security, email parsing, and packaging a web app into a native mobile app.
