Marine Trader Tracker
Internal loan tracking app for managing borrowers, repayment schedules, and daily collections. Includes ledger-based due/overdue visibility and transaction history.
Overview
Managing small-loan portfolios with varying interest accrual and payment schedules is error-prone when done manually. Staff need a fast way to see who is due or overdue, track partial vs. full payments, and keep a reliable record of all transactions.
Built a Firebase-backed web app that models each borrower’s ledger and calculates payment schedules based on interest ticks and payment intervals. The UI surfaces due payments and daily collection totals, while allowing staff to record payments, adjustments, and external cash movements securely behind Google-auth access control.
