Optimize Queries for Better Performance

Solved the Reverse Linked List problem using an iterative approach. The solution updates pointers step by step by reversing the direction of each node’s link, converting the list into its reverse without using extra space.

Some weeks in tech, you don’t build anything new. You just investigate, monitor, restart, compare logs, ask questions, and slowly narrow down one issue. And honestly? That’s real engineering too. Not every productive week ends with a feature release. Sometimes it ends with better understanding. The more I work in backend systems, the more I realize: Building is exciting. Debugging builds experience. #BackendEngineering #Learning #Java

🧠 Clean Code is Not About Fancy Code… Earlier, I used to think writing complex logic = good developer. But I was wrong. Now I follow one simple rule: 👉 “If a junior can’t understand it, it’s not clean code.” ✔ Meaningful variable names ✔ Small methods ✔ Less complexity Clean code saves hours of debugging later. Do you write code for machines or for humans? 👇 #CleanCode #Java #Developers #SoftwareEngineering

You don’t just become a better developer by writing more code — you grow by understanding systems, solving real problems, and continuously learning. From debugging issues to designing scalable solutions, every step adds to your experience. 💡 Focus on consistency, clean code, and learning — results will follow. #SoftwareEngineering #BackendDevelopment #Java #SystemDesign #CareerGrowth

Hello Everyone👋👋 What is method overriding? If a subclass provides a specific implementation of a method that is already provided by its parent class, it is known as Method Overriding. It is used for runtime polymorphism and to implement the interface methods. #Java #backend #frontend #FullStack #software #developer #programming #code #class #object #inheritance #lambda #super #constructor #SpringBoot #SpringAI #AI #GenAI #Java26 #Array #ArrayList #collections #Nodejs #Angular #React #AWS #interview

Today was a good day—but also a reality check. I spent hours diving into the Spring Framework and backend fundamentals. On paper, concepts like REST APIs, annotations, and dependency injection look simple. But when you actually try to understand how everything connects… it’s a different story. What really clicked today was the difference between tight coupling and loose coupling. It’s not just theory—it completely changes how you design scalable systems. Also explored autowiring and components in Spring Boot. Slowly starting to see how real-world applications are structured. Still learning. Still figuring things out. But one thing is clear: Consistency matters more than intensity. Back at it again tomorrow. #Java #SpringBoot #BackendDevelopment #LearningInPublic #DeveloperJourney #Consistency #Tech

Hello Everyone👋👋 Can we overload the main() method? Yes, we can have any number of main methods in a Java program by using method overloading. #Java #backend #frontend #FullStack #software #developer #programming #code #class #object #Array #ArrayList #collections #lambda #super #constructor #SpringBoot #SpringAI #GenAI #AI #OpenAI #Claude #Nodejs #React #Angular #AWS #Java26 #interface #abstract #interview

🧠 Phase 4: How Requests Are Handled (Real System Design) This is where things get serious. Every request follows this pattern: 👉 1 request = 1 thread Flow: Request hits server A thread is assigned Your code executes Response is sent back Thread is released Simple… but powerful. ⚠️ Here’s the catch: That thread is blocked until the request completes. So if: Your DB call takes 2 seconds That thread is stuck for 2 seconds Now imagine: 100 requests → 100 threads → potential bottleneck To manage this: Thread pools are used Requests are queued under load Limits are applied 💡 This is the foundation of backend scalability decisions If you understand this, you’ve already moved beyond most developers. #SpringBoot #Java #BackendDevelopment #SoftwareEngineering  #SystemDesign #WebDevelopment #Programming #Developers #Scalability #PerformanceEngineering #Concurrency  #SystemDesignInterview #BackendEngineering

Choosing between REST and GraphQL can impact how efficiently your application handles data. 🔹 REST APIs – Simple, widely used, ideal for standard CRUD operations 🔹 GraphQL – Flexible, fetch only required data, reduces over-fetching 🔹 REST is easy to implement, GraphQL offers more control 🔹 Choose based on your project needs Understanding both helps developers build efficient and scalable APIs. #Java #RESTAPI #GraphQL #JavaDeveloper #BackendDevelopment #FullStackDeveloper #WebDevelopment #Programming #SoftwareDevelopment
