I build the internal web tool your team actually needs: turn spreadsheets, paper forms and WhatsApp photos into a fast, mobile-friendly system.

What you get

Web app with login and user roles (React + Node.js + MySQL)

Interactive maps: GPS points, routes and zones

Dashboards with filters and key numbers

Automatic PDF and Excel reports

Works on phones, even without signal (offline PWA) if you need it

Deployed online and ready to use

Proven in production: the water utility system I built is used daily by 10 field technicians, with 35,000+ GPS points registered and around 400 illegal connections identified.

Great for field operations, utilities, logistics, inspections, municipalities and service companies.

How we work: a short call to define scope, weekly demos so you see progress, then delivery with 2 weeks of free bug fixes.

I work in Spanish and English.
