// ABOUT ME

Hi, I'm Alejandro

I've spent +5 years building SaaS products. I've worked with startups that raised funding rounds, and with companies billing millions.

My obsession is simple: ship products that work and make money. Not pretty code nobody uses. Real products that generate revenue.

✗ The problem

The client had a clear idea: a tool to collect feedback from SaaS users. He'd asked two agencies for quotes: €22k and €35k, with 2-3 months of development. He had neither that time nor that money.

✓ The solution

In 7 days I built: embeddable widget, analytics dashboard, Stripe subscription system, admin panel and an integrations API. All with Next.js, Supabase and Vercel.

Next.js 14 TypeScript Supabase Tailwind Stripe Vercel

What the client says

"Without Alejandro I'd still be waiting to have €30k to start. Now I have a product that bills and I can reinvest in growth."
