For a decade, Selenium WebDriver was the undisputed king of browser automation. But Microsoft’s Playwright has matured rapidly and provides a compelling alternative. Having migrated a massive E2E test suite from Selenium to Playwright, here is my detailed comparison. Architecture Comparison Selenium uses the WebDriver HTTP protocol. It sends an HTTP request for every action […]

Implementing Clean Architecture with .NET 5
Robert C. Martin’s “Clean Architecture” (or Onion/Hexagonal Architecture) is the gold standard for testable, maintainable enterprise systems. In this article, I will demonstrate how to structure a .NET 5 solution to enforce the Dependency Rule strictly. The Dependency Rule Source code dependencies must point only inward, toward high-level policies. The Inner circles (Domain) must not […]

Azure Logic Apps has traditionally been a Consumption-based, shared-tenant service. While cheap and scalable, it suffered from “Noisy Neighbor” latency issues and lacked VNET integration without an expensive ISE (Integration Service Environment). Detailed here is the new Logic Apps Standard, running on the Azure Functions runtime. Architectural Shift: Single Tenant Logic Apps Standard runs on […]

The landscape of software development is undergoing a seismic shift. I have spent the last week with the technical preview of GitHub Copilot, powered by OpenAI’s Codex model, and I can confidently say: this is not just “IntelliSense on steroids.” It is a fundamental change in how we write code. In this comprehensive review, I […]
Read more →Kubernetes Architecture: Beyond the Basics
Most tutorials explain Pods, Services, and Deployments. But running Kubernetes (K8s) in production requires understanding the control plane, the network model, and the reconciliation loop. In this article, we dissect the architecture of a high-availability K8s cluster and explored advanced scheduling patterns. The Control Plane vs Data Plane A K8s cluster consists of the Control […]

C# 9.0 is arguably the most significant update to the language since LINQ in C# 3.0. It introduces a functional paradigm shift with Records, cementing immutability as a first-class citizen. In this article, we will go beyond the syntax and explore how these features change the way we design Domain Models and DTOs. The Problem […]
