What this bullet means

The focus is careful transactional thinking: rates, invoices, balances, and reports need clear rules and a useful audit trail.

Sample app idea

Airport Fee and Invoice Tracker with rate rules, invoice drafts, payment status, adjustment reasons, and monthly reports.

Main build outline

  1. Create synthetic rate rules based on aircraft category, service type, effective date, and fee amount.
  2. Generate invoice drafts from approved activity and store the reason for every adjustment.
  3. Write tests for rate calculations, invoice totals, adjustment history, and invalid input.

Portfolio proof

  • Screenshots of rate rules, invoice calculations, and adjustment history using synthetic records.
  • Test output for calculation boundaries and invalid data handling.

Minimal documentation

  • README with the business problem, screenshots, setup notes, and technology stack.
  • One requirements note that maps the job bullet to the sample feature.
  • One test plan note with happy path, validation, and edge case checks.
  • One honest portfolio note that says this is self-directed practice, not employer work.

Modern .NET stack

  • Blazor Server or ASP.NET Core Razor Pages.
  • C# services with validation and dependency injection.
  • SQL Server locally, then SmarterASP SQL Server or Azure SQL.
  • Optional Azure App Service, GitHub Actions, Docker, and AI helper feature.
