Aprende Vibe Coding | Nov 2025 - Present

Aprende Vibe Coding

Building digital products with AI. Teaching people to launch products without coding. I created Aprende Vibe Coding - a framework to build and launch AI-powered products in days, not months. No technical background required. What I've built: Aiselfi.es - First product. Generated +$50k+ in revenue with zero coding experience. 100% bootstrapped. Multiple digital products — Launched consistently using the vibe coding methodology. What you'll learn from my journey: - How to monetize AI as a solopreneur. - How to build without being technical. - How to create landing pages, apps, and digital products using AI prompting, no-code development, and smart automation. The vibe coder's stack: - Lovable (AI app builder) - Supabase (database) - OpenAI + Gemini (AI integration) - Stripe (payment processing). Core beliefs: Speed beats perfection. Launch > perfect. Simple products sell. Complexity is a feature nobody asked for. AI is your co-founder, not your end goal. Consistency > talent. Launches > ideas. Your first product won't be your best, but it will teach you everything. I live 100% from my digital products, not clients. This course teaches how I build.

Que IA Es? | May 2025 - Present

Maker

Que IA Es? is an AI Tool Directory. It started as a personal side project to organize everything I was testing - but quickly became something more: a way to help Spanish-speaking users explore the world of AI without having to rely on English content. I built it for creators, makers, and professionals like me - who love tools, building things, and staying curious. It’s a solo project, fully vibe coded. I update it weekly.

I built the entire product myself using Vibe Coding, focusing on fast iteration, clean design, and solving one clear problem: making professional photos accessible to everyone. To date, aiselfi.es has generated over 80,000 high-quality photos, and this just getting started.
