1. Module Pattern

Encapsulates logic and avoids global scope pollution. Perfect for organizing frontend code.

const MyModule = (() => { const privateVar = 'Hidden'; return { publicMethod: () => console.log(privateVar), }; })();

2. Singleton

Ensures only one instance exists—great for configuration managers or logging services.

3. Factory Pattern

Creates objects dynamically (e.g., API clients for different environments).

4. Observer Pattern

Used in event-driven systems (like React’s state management).

5. Decorator Pattern

Adds behavior without altering original code (common in middleware).

Why This Matters: These patterns reduce bugs and make collaboration easier. Implement them in your next project!

2. How I Built a Scalable REST API with Node.js & Express

Building APIs is a core skill for backend engineers. Here’s my step-by-step approach:

Key Decisions

  • Folder Structure: Used layered architecture (controllers, services, models).

  • Error Handling: Centralized middleware for clean error responses.

  • Rate Limiting: Added express-rate-limit to prevent abuse.

Performance Tips

  1. Cached responses with Redis.

  2. Used helmet.js for security headers.

  3. Automated testing with Jest/Supertest.

Result: A 300ms average response time under load.

Your portfolio is your career lifeline. Here’s why:

1. Showcases Problem-Solving

Recruiters want to see how you built things—not just a resume bullet point.

2. Demonstrates Skills

  • Frontend? Include responsive designs.

  • Backend? Highlight API efficiency metrics.

3. My Portfolio Stack

  • Next.js (SSR for SEO)

  • Tailwind CSS (quick styling)

  • Vercel (zero-cost hosting)

Tip: Add a blog (like this one!) to boost SEO and authority.
