Loan Management System
End-to-end loan origination and servicing platform automating EMI calculations, repayment schedules, delinquency tracking, and regulatory reporting for a micro-lending institution.
A micro-lending organization was managing loan portfolios in spreadsheets, leading to calculation errors, missed payment follow-ups, and days spent preparing regulatory reports manually. This platform replaced all of that with automated, auditable workflows that financial regulators could inspect directly.
Financial calculations — compound interest, EMI schedules, partial prepayments, and penalty accrual — needed to be mathematically precise and immutably auditable. The system also had to handle edge cases like loan restructuring and early closure without corrupting historical ledger records.
Built a Laravel application with a double-entry ledger model ensuring every financial transaction is immutable and auditable. EMI schedules are pre-computed on disbursement and stored as amortization tables. PHP's BCMath library ensures full decimal precision for all financial arithmetic — no floating-point errors.

Implemented a double-entry ledger system ensuring full auditability of every disbursement, repayment, and fee transaction — each with a timestamp and user attribution.
- 02
Built an amortization engine supporting flat-rate and reducing-balance interest methods with penalty accrual for overdue loans and partial prepayment handling.
- 03
Created automated delinquency alerts with aging buckets (30/60/90 days) and email notifications to loan officers via Laravel queues.
- 04
Generated regulatory reports (portfolio at risk, collection efficiency, disbursement summary) as downloadable Excel and PDF with one click.
- 05
Eliminated manual EMI calculation errors, reducing average loan processing time from 45 minutes to under 15 minutes per application.
