Project description:
"I need a compact banking software tool that focuses on transaction processing. The first milestone is a working module that can execute and log fund transfers between accounts in real time, with the flexibility to accommodate other transaction types later.

Core requirements
• Fund-transfer engine: debit/credit logic, double-entry records, reversal handling, and daily reconciliation report.
• Security: token-based authentication, role-based access, encrypted data at rest and in transit.
• Integration: REST/JSON API that plugs directly into existing online banking portals; clear sample calls and webhook support for status updates.
• Audit & compliance: immutable transaction log, timestamped events, and basic fraud-alert hooks.

Deliverables
1. Functional prototype running on a test environment (Docker or similar) with documented setup instructions.
2. API documentation (Swagger/OpenAPI preferred) plus a short guide on embedding the tool in a typical online banking portal.
3. Source code, unit tests, and a brief hand-off session.

Tech stack is open; I’m comfortable with Java, .NET, or Node.js—choose what you can secure and scale quickly. Clean code, concise comments, and adherence to standard banking security practices are essential." (client-provided description)
