Quadra
An Android personal finance app for Panama and Latin America: track expenses, income, budgets, goals, debts, and recurring transactions, keep working offline, and speed up capture with OCR, Panama DGI tax QR scanning, and Quadra AI.
Problem
Many people stop tracking their finances because manual expense logging takes time, spreadsheets become heavy, and generic finance apps do not always fit the context of Panama and Latin America. Quadra reduces that friction with a local-first, fast experience built for daily use.
Role
Product design, technical architecture, mobile development, backend, data modeling, synchronization, OCR/AI integration, and commercial release planning.
