Saw this quote in Barcelona today. Love it

Time to shine!

AI is the future of coding Cursor / Copilot / Windsurf are changing how we write code. Here is everything you need to know about Cursor, how to use it effectively and the best rules andMCPs to get you started

I love how easy my life has gotten once I embraced AI IDEs to their full potential. (Agent, Ask, Rules, MCPs)

Wrote a piece on how I use Cursor:

YouTube video by Neciu Dan - The Señor Developer Build Instant Figma Components using Cursor

When I started Frontend Development, I had to build HTML & CSS from Photoshop.

This process could take days.

The Design Process has improved dramatically with Figma, but only now can you build Figma components in seconds with AI.
