Loan Management Platform

Problem: Lending operations mixed manual spreadsheet checks with ad-hoc tools. Repayment schedules, partial disbursements, and edge-case scenarios were error-prone and hard to audit.
Solution: Modeled loan lifecycle and repayment rules in a dedicated service layer with clear APIs, PostgreSQL for durable state, and a Nuxt dashboard for approvals, balances, and next actions.
Result: Automated loan repayment logic across multiple disbursement scenarios, reducing manual calculation errors and giving ops a single source of truth.
