About this gig
Hey, I'm Juan. I build SaaS platforms that actually work in production, not just pretty demos.
My main project is ElPotrero, a tournament management platform I built end to end. Web app, Android app on Google Play, real users, integrated payments, real-time data.
I work with Next.js, React, TypeScript, Supabase, and PostgreSQL. User auth, dashboards, payment integration, full platforms from scratch. That's what I do every day.
I'll ask the right questions, understand what you need, build it properly, and deliver something you can launch. Clean code, scalable architecture, no shortcuts.
English and Spanish. Send me your idea and I'll tell you honestly if I can help.

FAQ
Can you redesign my existing website?
Yes, I can redesign your existing website. I'll analyze your current site, understand what works and what doesn't, and rebuild it with a modern stack (Next.js + Supabase). You'll get a faster, cleaner, and fully responsive version. Just send me your current URL and tell me what you'd like to improve
Will my website be mobile-friendly?
Absolutely. Every site I build is fully responsive from day one. I develop mobile-first, meaning your app will look great on phones, tablets, and desktops. I use Tailwind CSS for precise control over every screen size. No extra charge, it's standard in all my packages.
Do you offer unlimited revisions?
Each package includes 2 to 5 revisions. I make sure we're aligned before coding, so most clients don't use them all. Need more? You can add extra rounds for a small fee.
What if I need more than 6 pages?
No problem. You can add extra pages for $50 each. For larger projects, message me first and I'll send you a custom quote based on your scope.
Do you provide hosting or domain?
I set up hosting on Vercel, the best platform for Next.js apps. Fast, reliable, free tier available. Domain registration is on your end, but I'll guide you and connect everything.
How do we communicate during the project?
Through Fiverr messages. I reply within a few hours and send regular progress updates. Before writing any code, we'll align on requirements, timeline, and expectations. No surprises.
Will my website include SEO optimization?
Yes. Proper meta tags, semantic HTML, fast loading, and clean URLs. Next.js has built-in SEO advantages like server-side rendering for better search engine indexing. Included in Standard and Premium.

Ridiculously fast! I asked Juan for a landing page for my air conditioning installing company and he literally went above and beyond to understand what I specifically needed. It's a fair amount of money for the beautiful work he did. Definitely worth trying.
