Mario S. Alvarez
I've been building on the web for more than 15 years.
I learned it in Latin America, kept at it in Canada, and I work from the Houston area now. To stay in Texas, I took rope access and NDT in the refineries. After a shift, I went back to the keyboard. I never left the web — I just grew up with it.
Search changed. Customers still use Google, but a lot of them also ask ChatGPT who to call. I run Zeroˣ Digit to help small business owners keep up with that: a site that works, a presence people can find, and less guesswork.
