Hi, I'm Joaquin Fuentes 👋

AI EdTech founder · Cybersecurity leader · Startup Advisor · Builder of practical, more secure AI experiences

I’m the founder of VibeVersity, where I’m building a community of creators, entrepreneurs and AI enthusiasts that want to learn by doing, not bookmarking. It's a community for tech-curious people looking to level-up, without going back to school. My creative work sits at the intersection of AI engineering made simple, cybersecurity, and creator-first hands-on product building.

VibeVersity

OSCP CISSP CISA CEH CPT

AWS Certified Solutions Architect – Associate

What I do

  • Build simple and practical AI learning experiences that lead to deployed, adopted and attention grabbing work
  • Bring security and privacy safeguards into AI projects from the start = 'more secure'
  • Help professionals and teams turn AI curiosity into useful, repeatable workflows

Security community, CTFs & speaking

What I stopped doing

I stopped measuring progress by how much code I could write by hand. In 2024, I completed a six-month, hands-on AI certification program at Arizona State University, where I trained models and used Python libraries to solve real-world problems. Moving quickly required us to accelerate development with AI coding assistants. Since then, I’ve found that vibe coding with AI can match the output quality of some of the best human programmers at speeds we simply cannot match, though often at the cost of durability, scalability, and security. That foundation now helps me direct AI-assisted development with purpose instead of spending my time engineering ephemeral primitives. I’ll leave that to the principal engineers.

Good vibes

Vibe coding gives me more time to focus on the parts of building that matter most: shaping useful ideas, solving real problems, sharing what I learn, and helping other people create something customers use every day. At the core of it all, everything starts with the end user, and we should all be customer obsessed.

My favorite ASU AI project was the SMiShing & Scam Detector. Send it a suspicious text or screenshot, and it assesses whether the message is likely a scam while explaining the warning signs in plain language. I built it for people like my mom—because security tools are most valuable when they are understandable and easy to use.

A little GitHub plot twist
For much of my career, my development work lived in GitLab and other solutions. In 2026, I decided to move to GitHub. This activity graph tells the latest chapter, not the whole story. So, I'm enjoying seeing the green squares fill up. I hope yours also bring you joy.
