Building a Scalable REST API with ASP.NET Core

Introduction
In today’s connected world, APIs are the backbone of modern applications. As a .NET developer, one of my most impactful projects was designing a scalable REST API using ASP.NET Core. This post breaks down my approach, challenges faced, and lessons learned.

Main Body

• Project Background: The client required a high-performance API to support thousands of concurrent requests.
• Tech Stack: ASP.NET Core, Entity Framework Core, SQL Server, Swagger, and JWT Authentication.
• Architecture Choices: Clean Architecture with layered design for separation of concerns.
• Key Features Implemented:
  • Authentication & Authorization with JWT.
  • Efficient database queries using LINQ and EF Core.
  • Swagger for auto-generated documentation.
• Challenges & Solutions: Optimizing query performance and handling concurrency issues.
• Outcome: Reduced response times by 40% and scaled to 50,000 requests/day with minimal downtime.

Conclusion
This project highlighted the power of ASP.NET Core in building reliable APIs. It reinforced my belief in designing for scalability from the start.
