Treasury Management Platform (NDA)

A treasury platform's single hub for cash, vault, receipts, collections & counterparties.

The problem: A company's treasury team needed a single place to manage cash and liquidity; vault, cash receipts, collections, and counterparty operations, rather than fragmented tools, in a startup-like environment with early technical debt to control.

What I did: I built the platform from scratch, including architecture, backend, and frontend, and drove down early technical debt as the codebase grew. (Product and client name withheld under NDA.)

A from-scratch OAuth2/OIDC identity server (IdentityServer4), the security foundation

A .NET 5 resource API and an Angular 12 SPA covering vault, cash-receipt, collection, and counterparty operations

SQL Server data layer with T-SQL stored procedures

Set the architecture and kept technical debt down single-handedly

Outcome: A working treasury & cash-management platform owned end-to-end.

Tech: Angular 12 - .NET 5 - C# - IdentityServer4 - OAuth2/OIDC - SQL Server (stored procedures).
