A year ago, I uploaded my first Udemy course - "Modern Angular with Signals – The Missing Guide."

What started as a way to fill a gap for my mentees turned into something far bigger: thousands of students from over 100 countries, a 4.83 average rating, and 85% 5-star reviews.

Angular Material 19 gives you way more power to customize components and match your brand — but only if you understand how it works.

My new Udemy course breaks it down + shows how modern CSS makes theming a breeze.
