For the first time, I built a CI/CD pipeline for my Android project using GitHub Actions and Firebase App Distribution. Read here linkedin.com/posts/tikeshwa…

Android OS Architecture — Layer 3 Native Libraries — The City’s Heavy Machinery If the Kernel is the foundation and HAL is the universal adapter, then Native Libraries are the power plants and factories of the city. Read here👇 linkedin.com/posts/tikeshwa…

🧠 Android OS Architecture — Explained Like a Smart City 🏙️ Think of Android not just as an operating system, but as a smart city where millions of apps (citizens) live and work smoothly every day. Each layer has a clear responsibility. Read here👇 linkedin.com/feed/update/ur…

WHY System Design Exists 🚀 Before jumping into tools, frameworks, or architectures—first understand the problem. When your app has 👤 100 users → everything works smoothly 👥 1 million users → suddenly things break Read here👇 linkedin.com/feed/update/ur…

How to Calculate Time Complexity (O(1), O(n), O(n²), O(log n)) Many people think Time Complexity is hard. It’s not — if you follow one simple rule from DSA fundamentals Read here👇 linkedin.com/feed/update/ur…

@manojdotdev Back then in class 12th I studied python but didn't know how to write code we actually considered it as a subject only. But I started with Java.

in which language you wrote your first "hello world"?

@teja2495 I also built an app for my own use for learning words daily it's like reminding you to learn new words ! 😁

I built an app called “My App” for my own use and I am not publishing it anywhere. Whenever I need a feature on Android, I add it to my app instead of searching for apps on play store. Since I am both the developer and the user, I can give it any permissions it needs and build exactly what I want without worrying about privacy! 😄

@VishonSingh Yeah the edge case is very important to understand when you want to optimise something.

@Tiku__z Yeah, and understanding those cases helps a ton when you're optimizing for real-world scenarios, not just textbook problems. It's all about the trade-offs!

Best, Average & Worst Case (Interview Preparation Example) When we talk about Time Complexity, an algorithm can behave differently depending on input. That’s why we analyze it in three cases. Read here 👇 linkedin.com/posts/tikeshwa…

Dominant Term: The Real Secret of Time Complexity In Time Complexity, not all code lines matter equally. Read here 👇 linkedin.com/feed/update/ur…

Understanding Why Time Complexity Matters. When we write code, the first question is not 👉 “Does it work?” but 👉 “How well does it work when input grows?” Link for details - linkedin.com/feed/update/ur…

🧠 Jetpack Compose state finally has a missing piece We had a gap: • remember → survives recomposition, not rotation • rememberSaveable → survives rotation, but needs serialization So what about: controllers, players, bitmaps, non-serializable.👇linkedin.com/feed/update/ur…

🧠 How ViewModel Works Internally (Android) ViewModel survives rotation not because Activity lives, but because Android retains the ViewModelStore. Under the hood 👇 Full Detail - linkedin.com/feed/update/ur…
