Financial Disbursement Management System

Centralize disbursements, payment validation, installments and financial reporting.

Operational context

A financial operation supported by local files and manual checks, with information scattered across different roles.

A web system that structures the operational flow, centralizes information and improves payment and disbursement traceability.

The flow shows how responsibilities are separated from the HTTP entry point through persistence. The yellow layer holds the business rules.

Architecture5 layers

Separated the API, business rules, interface and persistence responsibilities to reduce coupling and simplify maintenance.

Depends on Use cases

Exposes the 147 REST endpoints behind a JWT session and hands each request to a use case, without making any business decision.

Depends on Disbursements domain

Coordinates each operation end to end (disbursement, payment, installment, rescheduling) on top of the domain.

Depends on Business rules

Models loans, payments, installments, portfolio and arrears: the core the rest of the system wraps around.

Depends on Persistence and audit

Gathers the payment checks that used to be done by hand, so they are always applied the same way.

Depends on no other layer

Stores every operation with its date and owner; financial reports are built from these records.

147 REST endpoints behind a JWT session: loans, payments, installments, portfolio, arrears and rescheduling.
21 unit and feature test suites over the critical rules: authentication, payments, arrears, portfolio, rescheduling and calculator.
Manual payment-validation steps cut by 50%, measured against the previous process.
Financial reports generated from system records instead of parallel spreadsheets.

The project turns scattered operational rules into a traceable, tested, and maintainable system.

Let’s discuss the workflow, rules, and architecture your system needs.
