/**

* I started coding at 18 and never stopped. I worked in the corporate world writing ABAP for a large company, but my true passion was always the web.

* Since 2009 I specialized in web development and SEO. For years I balanced my job with personal side projects.

* In 2020, during lockdown, I went independent. Today I work on what I love: building websites, ranking brands, and exploring AI.

My evolution using AI for programming: from lunch to the terminal

As a programmer, artificial intelligence has always fascinated me. One idea that kept coming up was being able to talk to computers in natural language, to program without hardly touching the keyboard. It seemed like science fiction. You could say that moment has arrived.
