About me
I build software businesses actually run on. Stores, internal systems, automations. A pharmacy chain was stuck on a slow WooCommerce site. I rebuilt it on Next.js, live now and synced to Meta Commerce. A pharma plant ran on spreadsheets until I built them a real system. A restaurant takes orders through a WhatsApp bot I built. On the side I ship my own Android apps on Google Play. Backend is where I'm strongest. Node, NestJS, PostgreSQL, React and Next.js on top. I'm in Bolivia, online during US business hours. Tell me what you're building and I'll tell you honestly if I'm the right fit.... Read more
