Hi, I'm Ivan.
Ivan Antonio Hernández Guzmán · AI data annotator · San Luis Potosí, Mexico
I write Hydrael to explain, in plain language, three things I use every day: artificial intelligence, crypto, and how world events affect your money. I write from what I test and learn, and I always cite my sources so you can check them yourself.
From customer service to training AI
I have more than 10 years of experience in bilingual customer service, hotel sales and logistics. That's where I learned to explain complicated things simply and to listen to what people really need.
Today I work remotely on projects that train artificial intelligence. I transcribed and labeled Mexican Spanish audio to train speech recognition on a TELUS International project, and I've done AI response evaluations on other annotation platforms.
From my desk in San Luis Potosí
This is where I do my AI projects, test the tools I review and write every article. When I talk about a platform, an exchange or a tool, it's because I used it or researched it with official sources.

What I'm not
How this site makes money
I'd rather you know from the start. No company pays to appear in an article or reviews what I write before it's published.
If you sign up for an exchange with my link, I get a commission. It costs you nothing extra and I always disclose it.
I'm preparing my first guide: how to connect Claude to Bybit to trade with supervision.
Some tools I recommend, like Canva or Netlify, have affiliate programs. I only recommend what I use.
