Lessons Learned: Building Cloud-Native Microservices with ASP.NET Core 9 for Our Enterprise Client

Lessons Learned: Building Cloud-Native Microservices with ASP.NET Core 9 for Our Enterprise Client

A Real-World Journey from Requirements to Production Hey fellow developers and architects! 👋 I wanted to share some insights from a recent project we completed for a major retail client who needed to modernize their monolithic e-commerce platform. They came to us with a classic story: "Our system is slow,

Streamlining Microservice Communication: How Refit HTTP Clients Power Our Distributed Architecture

In the world of modern software development, microservices architecture has become the gold standard for building scalable, maintainable applications. However, with this architectural approach comes the challenge of seamless inter-service communication. Today, I want to share how we've leveraged Refit, a powerful REST library for .NET, to create

Building Modern, Observable .NET Applications: A Deep Dive into OpenTelemetry, Scalar, and OpenAPI Integration

Building Modern, Observable .NET Applications: A Deep Dive into OpenTelemetry, Scalar, and OpenAPI Integration

In today's distributed application landscape, observability isn't just a nice-to-have—it's an absolute necessity. When you're running multiple microservices across different environments, understanding what's happening inside your applications becomes critical for maintaining performance, debugging issues, and ensuring reliability. In this

Domain-Driven Design with Onion Architecture in .NET 9: Building Scalable Microservices

Domain-Driven Design with Onion Architecture in .NET 9: Building Scalable Microservices

In modern software development, creating systems that are maintainable, testable, and adaptable to change is crucial. Our platform showcases a real-world implementation of Domain-Driven Design (DDD) combined with Onion Architecture principles, all built on .NET 9. This architectural approach has allowed us to develop a robust microservices ecosystem that delivers
