🤝 LendFlow - P2P Escrow API & State Machine

LendFlow is an enterprise grade FinTech Escrow API designed to securely manage Peer-to-Peer (P2P) freelance transactions. It acts as the trusted middleman, ensuring funds are securely locked and released only when strict business conditions are met.

🏗️ System Architecture

This project demonstrates a modern Decoupled Monorepo approach:

• Backend (/Backend-API): A headless C# .NET 8 Web API utilizing strict N-Tier Architecture (API, BLL, DAL).
• Frontend (/Frontend-Dashboard): A lightweight, decoupled Vanilla JS client that consumes the API data asynchronously.

⚙️ Core FinTech Engineering

1. The State Machine Pattern: The core of the business logic. Transactions are strictly enforced to move linearly: Pending ➔ Funded ➔ Delivered ➔ Released (or Disputed / Refunded). Code prevents race conditions and illegal fund movements.
2. Financial Data Integrity: Entity Framework Core is configured with strict SQL column typings decimal(18,2) to prevent floating-point rounding errors during wallet transactions.
3. Data Engineering (Seeding): To simulate a live platform, the database automatically ingests a Kaggle Freelance Job Dataset. On startup, it dynamically builds Client/Freelancer profiles, funds digital wallets, and generates escrow contracts.
