Andrés Sepúlveda Morales
Three corporate layoffs in two years will do something to you. For me, it meant building Red Mage, where I work with people whose missions I believe in.
I'm a Puerto Rican technologist based in Barcelona. I've worked in tech for about 9 years, and Red Mage has been my practice since December 2023. I build websites, AI tools and automations for nonprofits, B Corps, Latino-led businesses and founders, in English or Spanish.
I also teach AI to people who find it intimidating.
