WTFast
The product was quietly lying to its users. Design didn't fix that. Diagnosing it did.
4× activation. 3× revenue. The CTO told me design wasn't the problem. That's why it worked.

I'm Fernando. I work with founders, teams, and agencies on the gap between it functions and it feels inevitable. That's where retention, trust, and growth actually live.

Three products that didn't feel like home, until they did.
None of these were surface-level design problems. Each one needed somebody close enough to the user, the engineer, and the business to see what was actually breaking.
Party Parrot World
A social game where socializing was hard. The Discord told us before the metrics did.
Players stopped complaining about the chat. They started chatting like they always had.

United Gamers
Founders who knew the science, missed the player. I'd been the player for five years.
€250k seed. The pitch worked because the product finally did.

I don't wait for engineering to validate ideas. I build with AI: products of my own, prototypes for clients, and the workflows other product designers use to do the same.
ArturoMed
Scheduling and medical records for private practices in Ecuador: online booking, prescriptions and reports in one place. Born inside a real practice, now sold to other doctors.

I also teach this.
The designers who show up to my workshops come from teams at MercadoLibre, EY, Banco Guayaquil, and other companies across LATAM, including industries that don't usually have a design team. The pattern repeats: once they've built something real with AI, they stop asking permission to do it again.
Working with Fernando gave me vibe coding foundations I didn't have before. He explains everything clearly and makes sure you actually learn it. I'm taking this into both client work and personal projects.
As a designer I'd always avoided the technical side. Fernando teaches GitHub and how to actually run an AI-built product without making it overwhelming. With Claude Code as a real dev copilot, I now have the tools to ship my own ideas without depending on anyone.
Fernando goes straight to the point. You build real products, no excess theory, just the day-to-day calls that actually matter. If you want to go from idea to MVP without going in circles, this is worth it.
I don't know how to code, and Fernando proved that's not a blocker for building with AI. He doesn't just hand you steps. He explains the foundations and why they matter. That's the difference between executing and actually understanding what you're building.
Exceeded my expectations. We worked step-by-step on real projects, and shipped a custom Trello clone to production. Hands-on: shared screens, problems solved live. If you want to apply AI to product design, Fernando gives you the concrete leap.
Writing
Notes from the field on AI-driven product design, vibe coding, and building systems that ship.
I Never Meant to Build Medical Software. Now I Sell It.
How a side project for my sister's practice became ArturoMed, commercial medical software in Ecuador, and what charging for it taught a Product Designer.
I Had 56 AI Agents Installed. I Was Using One.
How I audited my Claude Code setup with real usage data, archived 90% of it, and got better results for fewer tokens. A cleanup method for product people.
Loop Engineering: Stop Prompting Agents, Start Designing the System That Prompts Them
Loop engineering replaces you as the person who prompts the agent. You design the system that does it instead — five pieces, one memory, and a verifier you trust.
Behind the work
I came to product design through architecture, content creation, and marketing. Three different ways of seeing how things hold together.
Architecture taught me systems. Content taught me audiences. Marketing taught me what a business actually pays for. That's the lens behind every product I touch.
