À propos de ce service
Do you need a custom web application where users can sign up, log in, and access their own data? I build complete, working multi-user web apps not just designs or mockups.
WHAT I DELIVER:
- User authentication with Firebase (secure login & signup)
- Real-time database (Firestore) to store and manage data
- Admin panel to manage users and content
- Clean, responsive design that works on mobile and desktop
- Payment integration available (Stripe / MercadoPago)
PERFECT FOR:
- Business dashboards and internal tools
- Membership platforms
- Custom calculators and management apps
- Startups validating an idea (MVP)
WHY ME:
With 15+ years of business experience, I understand real-world needs not just code. I deliver functional products ready to use, with clear communication from start to finish.
Every project is built to work. Message me before ordering so we can discuss your idea and I can recommend the best package for you.

FAQ
Do I need technical knowledge to use the app?
Not at all. I deliver everything ready to use, and I explain how to manage it. The admin panel is designed to be simple.
Can users create their own accounts?
Yes. The app includes secure signup and login powered by Firebase, so each user has their own account and data.
Will the app work on mobile phones?
Yes. All apps are responsive and work smoothly on phones, tablets and desktop.
What do you need from me to start?
Just a clear description of what your app should do. If you have examples or references, even better. We can discuss details in chat.
