Project Overview
An end-to-end retail lending and secured loan origination platform developed with ReactJS and C# .NET Core for a leading national consumer finance and secured lending network. The system digitizes the entire credit lifecycle across nationwide transaction offices: from instant citizen credit checks, automated collateral valuation (motorbikes, cars, property registration deeds), dynamic multi-tiered amortization schedule generation (principal, interest, asset management fees, loan servicing fees), to multi-step e-dossier KYC upload with geo-location verification, and automated 24/7 instant disbursement via the Napas interbank payment gateway.
Challenges & Pain Points
Slow Branch Paperwork & Disconnected Systems
Traditional branch-based loan initiation relied on physical paperwork, manual appraisal calls, and detached spreadsheets. Loan officers spent 2 to 4 hours per applicant manually verifying national IDs, re-typing customer profiles, and estimating collateral values.
Collateral Duplication & Fraud Exposure
Without a real-time centralized registry, borrowers could pledge the same vehicle or property title across multiple branch locations simultaneously, creating severe credit risk and unrecoverable loan losses.
Complex Multi-Tier Fee & Interest Amortization
Consumer lending products involve intricate fee structures: monthly nominal interest, loan servicing fees, asset storage/management fees, and early repayment penalties. Manual calculation frequently produced rounding discrepancies and customer disputes.
Disbursement Delays & Banking Hours Constraints
Approved loans required manual teller cash payouts or standard banking transfers that were unavailable during weekends and evenings, leaving emergency loan borrowers waiting up to 24 hours.
Our Solution
5-Step Automated Loan Origination Pipeline (ReactJS)
Engineered an intuitive, high-speed 5-step ReactJS workflow: 1. Instant identity credit validation; 2. Asset selection and anti-duplicate check; 3. Dynamic package selector with automated limit estimation; 4. Detailed customer profiling and e-dossier document upload; 5. Automated branch routing for maker-checker sign-off.
Real-Time Asset Valuation & Anti-Duplication Engine (C# .NET)
Developed a high-throughput C# .NET valuation engine with SQL Server asset locks. The system cross-references vehicle frame numbers, license plates, and property IDs to enforce a strict one-active-contract rule (`CheckAssetUsingOnlyContractActive`) while calculating dynamic maximum loan ceilings (`GetFinalLimit`).
Dynamic Multi-Tier Amortization Schedule Engine (<50ms)
Built a specialized calculation engine with Redis caching capable of generating complete multi-year repayment amortization schedules in under 50ms. Transparently breaks down monthly payments into principal, interest, loan management fee (QLKV), asset management fee (QLTS), and remaining balance across all term tenors (3 to 24 months).
e-Dossier KYC, Geo-Location & Napas 24/7 Instant Disbursement
Integrated client-side image compression for multi-photo KYC dossiers (identity cards, vehicle inspection photos, income proofs), Google Maps geo-coordinate validation for residential verification, and real-time Napas 24/7 gateway integration for automated direct-to-account disbursement immediately upon contract approval.
Technology Stack
Lending & Retail Finance Domain Expertise
Secured Consumer Lending & Collateral Governance
Deep domain mastery of retail consumer lending regulations, collateral depreciation models (motorbikes, cars, registration documents), fund source allocations, and branch risk-mitigation policies.
Contract Lifecycle & Exception Handling (YCBS)
End-to-end management of complex contract state machines: Draft Contracts, Pending Branch Review, Supplemental Document Requests (YCBS), Approvals, e-Signatures, Active Servicing, and Early Settlement.
Interbank Napas 24/7 & Digital Identity Ecosystem
Expert implementation of Napas 247 account inquiry and fund transfer APIs, digital identity verification, secure maker-checker token handshakes, and automated payment webhook callbacks.
