If you are learning OOP in C# or preparing for C# interview questions, one concept you must understand is the Interface in C#. Don’t worry if it sounds complicated – we’ll break it down step by step, in a simple way, just like a teacher explaining to beginners. 🌟What is an Interface in C#? Think […]

What is Interface Segregation Principle (ISP)? The Interface Segregation Principle (ISP) is the “I” in SOLID principles. It states: 👉 Clients should not be forced to implement interfaces they don’t use. In simple terms: instead of designing one large fat interface in C#, split it into smaller, role-specific interfaces. This makes your code cleaner, testable,

In today’s fast-paced world of web and mobile app development, state management is at the heart of building scalable, maintainable, and high-performance user interfaces (UIs). Whether you’re building a React web dashboard, an Angular enterprise application, or crafting modern mobile UIs with Jetpack Compose (Android) or SwiftUI (iOS), how you manage application state directly impacts:

In the world of software development, building scalable and maintainable code is a top priority. One of the most powerful design guidelines that helps developers achieve this is the Open/Closed Principle (OCP), a core concept in SOLID principles of object-oriented programming. What is the Open/Closed Principle? The Open/Closed Principle states that software entities (classes, modules,

In modern software development, writing clean, scalable, and maintainable code is essential. One of the core concepts that helps developers achieve this is the Single Responsibility Principle (SRP)—a fundamental part of the SOLID principles in object-oriented programming. What is the Single Responsibility Principle? The Single Responsibility Principle states that a class, module, or function should

Unlocking Cleaner, Smarter Code Ever wondered how top developers keep their code easy to evolve, test, and maintain? Enter SOLID—a smart acronym for five rock-solid design principles in object-oriented programming, introduced by Robert C. Martin around 2000 . What’s Behind the Letters? S – Single Responsibility Principle (SRP) A class should have only one reason

Building an Android app no longer requires weeks of coding and design work. Thanks to AI tools, I was able to go from idea → prototype → Jetpack Compose code → running app in just 1 hour. Here’s exactly how I did it. Step 1: Idea Generation with ChatGPT Instead of brainstorming for days, I

A technical interview is a structured conversation: your goal is to demonstrate problem solving, system thinking, and fit. Prepare the right topics, present clearly, and engage professionally. 1) Research: company technology details + partners (what to learn & say) Before the interview, gather: primary languages/frameworks, cloud/infrastructure (AWS/GCP/Azure), data stores, messaging systems, and key partners (payments,

When microservices start multiplying, complexity follows. Domain-Driven Design (DDD) gives you the language, boundaries, and patterns to keep systems understandable, scalable, and ready for change. Here’s a short, no-fluff guide with a concrete example you can mirror in your next project. Why DDD fits microservices Core concepts (30-second refresher) A quick example: E-commerce order flow

Jetpack Compose 1.9, released in August 2025, introduces two game-changing visibility modifiers—Modifier.onVisibilityChanged and Modifier.onFirstVisible—bringing precision, performance, and clarity to UI behavior without resorting to tricky LaunchedEffect hacks. 1. Modifier.onVisibilityChanged Want to auto-play videos, start animations, or trigger logic as your composable appears or disappears? This modifier lets you react to visibility changes—with optional thresholds for
