OOP and maintainable application design
Healthcare Technology
Use object-oriented design and clear patterns to keep business rules understandable as the application grows.
What this bullet means
The team wants code that another developer can extend. Good models, focused services, dependency injection, and tests are more valuable than a large page full of mixed logic.
Sample app idea
Eligibility Rules Engine with C# domain models, validation services, rule evaluation results, and explainable decision notes.
Main build outline
- Create domain models for request, participant, eligibility rule, result, and audit note.
- Put validation and rule evaluation inside focused C# services.
- Write tests that show valid, invalid, and edge-case rule outcomes.
Portfolio proof
- C# code example showing domain models and a focused business-rule service.
- Test output covering expected and edge-case eligibility decisions.
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.
