.NET / ASP.NET Core

ASP.NET Core is the backbone of Voice Up Athletics, the multi-tenant SaaS platform I'm building for an actual company as my senior capstone. It's a high-performance, cross-platform framework and working with it at this scale has given me a real appreciation for enterprise-grade backend architecture — dependency injection, middleware pipelines, JWT auth, and cloud deployment are all things I do daily with this stack.

Expertise Areas

Web API Development

• RESTful Controllers - Attribute routing, versioning, status codes
• Minimal APIs - Lightweight endpoint handlers for simple routes
• Middleware Pipeline - Custom middleware for auth, logging, error handling
• Filters - Action filters for cross-cutting concerns
• Response Formatting - JSON serialization, content negotiation

Authentication & Authorization

• JWT Bearer Tokens - Validating tokens issued by Microsoft Entra ID
• Policy-Based Auth - Custom authorization policies and requirements
• Role-Based Access Control - Scoping endpoints by role (Athlete, Admin, SuperAdmin)
• Claims Transformation - Extracting tenant and role from JWT claims

Dependency Injection & Architecture

• Service Registration - Scoped, transient, and singleton lifetimes
• Clean Architecture - Separation of Core, Infrastructure, and API layers
• Repository Pattern - Abstracting data access behind interfaces
• Configuration - IOptions<T> pattern, environment-based settings

Entity Framework Core

• Code-First Modeling - Database schema from C# entity classes
• Migrations - Versioned schema changes and rollbacks
• Querying - LINQ queries, projections, includes
• Multi-Tenant Scoping - Global query filters for tenant isolation

Projects Using .NET / ASP.NET Core

Voice Up Athletics — Senior Capstone (Real Client)

Technologies: .NET 10, ASP.NET Core Web API, EF Core, Azure SQL, Microsoft Entra ID The entire backend is an ASP.NET Core Web API, designed from scratch with enterprise patterns in mind:

• Clean Architecture with strict layer boundaries — domain logic never touches infrastructure
• Multi-tenant middleware resolves the active tenant from Entra JWT claims on every request
• EF Core global query filters guarantee tenant data isolation at the database layer
• Deployed to Azure App Service via Azure DevOps CI/CD pipelines
• Single API serves both the Next.js web client and Expo React Native mobile app

• JWT auth, refresh tokens, and role-based authorization
• Azure App Service deployment and configuration

Why I Love .NET / ASP.NET Core

ASP.NET Core surprised me with how clean and opinionated it is compared to Node/Express. The built-in DI container, middleware pipeline, and configuration system give you a solid production-grade foundation without stitching together a dozen packages. Working on an actual enterprise project has shown me why .NET dominates in large organizations — the tooling, the performance, and the architecture patterns it encourages all scale beautifully.

Current Focus

• Advanced middleware and filter pipelines
• Background jobs with IHostedService and Hangfire
• gRPC services alongside REST
• Integration testing with WebApplicationFactory
• SignalR for real-time features in VUA
