This blog is where I share my learnings, experiences, and insights from my journey in software development. What I’ll Be Writing About My primary focus is backend development, so you can expect posts covering: API Design & Development - RESTful APIs, GraphQL, best practices Database Systems - SQL, NoSQL, query optimization, data modeling System Design - Scalability, microservices, distributed systems DevOps Essentials - Docker, CI/CD, deployment strategies Backend Frameworks - Spring Boot, Node. /blog/building-restful-apis-best-practices/ Fri, 10 Jan 2025 00:00:00 +0530 /blog/building-restful-apis-best-practices/ Building APIs is at the core of backend development. Whether you’re creating a service for a mobile app, a web application, or other microservices, following best practices ensures your API is intuitive, maintainable, and scalable. 1. Use Meaningful Resource Names Your URLs should be nouns, not verbs. Resources represent entities in your system. ✅ Good: GET /users GET /users/{id} POST /users PUT /users/{id} DELETE /users/{id} ❌ Bad: GET /getUsers POST /createUser DELETE /deleteUser/{id} 2. /blog/database-indexing-explained/ Sun, 05 Jan 2025 00:00:00 +0530 /blog/database-indexing-explained/ If you’ve ever wondered why some queries are blazing fast while others take forever, the answer often lies in indexing. Let’s dive into how database indexes work and how to use them effectively. What is an Index? An index is a data structure that improves the speed of data retrieval operations on a database table. Think of it like the index in a book—instead of reading every page to find a topic, you look it up in the index and go directly to the right page. /blog/understanding-microservices-architecture/ Fri, 20 Dec 2024 00:00:00 +0530 /blog/understanding-microservices-architecture/ Microservices have become a buzzword in backend development. But what exactly are they, and when should you use them? Let’s break it down. Monolith vs Microservices Monolithic Architecture In a monolith, all components are part of a single, unified codebase: ┌─────────────────────────────────────┐ │ MONOLITHIC APP │ ├─────────────────────────────────────┤ │ User Service │ Order Service │ │ Payment │ Notification │ │ Inventory │ Analytics │ ├─────────────────────────────────────┤ │ Single Database │ └─────────────────────────────────────┘ Pros: /blog/docker-for-backend-developers/ Sun, 15 Dec 2024 00:00:00 +0530 /blog/docker-for-backend-developers/ Docker has revolutionized how we develop, ship, and run applications. As a backend developer, understanding Docker is essential. Let’s explore how to containerize your backend apps. Why Docker? “It works on my machine” - We’ve all heard this. Docker solves this by packaging your application with all its dependencies. ┌─────────────────────────────────────┐ │ Docker Container │ ├─────────────────────────────────────┤ │ Your Application │ │ Runtime (Node.js, Python, Java) │ │ Dependencies │ │ System Libraries │ │ OS (Linux) │ └─────────────────────────────────────┘ Core Concepts Images vs Containers Image → Blueprint (like a class) Container → Running instance (like an object) Dockerfile A Dockerfile is your recipe for building an image:
