🔐 JWT (JSON Web Token) Cheatsheet Every Developer Should Bookmark! 🚀

If you're building authentication systems, JWT is a must-know skill. Here's the ultimate JWT cheatsheet:

✅ JWT Structure: `Header.Payload.Signature`
✅ Authentication & Authorization
✅ Access Tokens vs Refresh Tokens
✅ Token Generation & Verification
✅ Secret Key Management
✅ Expiration (`exp`) & Issued At (`iat`)
✅ User Claims & Custom Claims
✅ Bearer Token Authentication
✅ Token Refresh Flow
✅ Secure Storage Strategies
✅ JWT Middleware Protection
✅ Common Security Best Practices

⚡ Pro Tip: Never store sensitive data inside the JWT payload. Always use short-lived access tokens and secure refresh token strategies for production applications.

Save this JWT cheatsheet—you'll thank yourself during your next authentication project! 🔥

Excited to share a look at my latest UI/UX project: A complete design overhaul for an automotive and mobility platform. 🚗✨ For this redesign, I focused on creating a premium, modern feel by shifting to a sophisticated dark teal and warm terracotta color scheme, moving away from the traditional white.
​I structured the new layout to highlight distinct categories—like EV Charging Solutions, Performance Tuning, and Luxury Rentals—making product discovery much easier and more intuitive for users. The entire project was built from scratch to showcase a fresh perspective on what an auto-eCommerce platform can be. Feedback is always welcome!
