VaultIQ: ASP.NET Core 8 and Angular 18 in Clean Architecture
What does a Clean Architecture project with ASP.NET Core 8 and Angular 18 Signals look like?
VaultIQ is an AI startup-idea generator laid out the way enterprise .NET teams build to last: an ASP.NET Core 8 Web API in four Clean Architecture layers with EF Core and SQL Server, and an Angular 18 front end built from standalone components with Signals for state.

01The problem it solves
Prototypes get rewritten the moment a second client arrives. VaultIQ is the enterprise half of the range: a deliberately small product built with the structure a real .NET + Angular team would use, so it could survive that second client.
02What he built
Back end: four layers
An ASP.NET Core 8 Web API split into four Clean Architecture layers, with EF Core over SQL Server (run locally in Docker), so business rules don't depend on the database or the web framework.
Front end: Angular 18 with Signals
Standalone components and Signals instead of NgModules and ad-hoc subscriptions, and a landing page in the product's own violet-and-pink brand.
03 — THE HARDEST DECISIONStructure first, even for a small product
Clean Architecture costs more files on day one. The trade is that each layer can be tested and replaced on its own — the same reasoning behind Sarthi's separately testable pipeline stages, applied to a conventional enterprise stack. It mirrors how Shreyansh builds production systems at RamanByte: the API contract and the schema first, then the client that consumes them.
04The result
A .NET 8 and Angular 18 codebase that shows the enterprise patterns hiring teams look for — layering, separation of concerns, Signals — in a product small enough to read in an afternoon.
