About this gig

Need a custom web app or SaaS for your business? I build responsive web applications with JavaScript and Firebase, from idea to launch.


What I can build for you:

- Web apps with user login and accounts

- Dashboards and data panels

- Firestore databases with secure access rules

- Admin panels to manage users and content

- Online payments and subscription plans

- Multi-language apps (English/Spanish)

- Mobile-friendly, responsive design


Why work with me:

- Real experience: I built PokerDataOS (pokerdataos.com), a poker analytics SaaS with dashboards, payments, an admin panel and 200+ automated tests.

- I test every flow before delivery.

- AI-assisted development: I use AI tools to work faster, and I review and test all the code.

- You get the full source code.


How it works:

1. Tell me your idea.

2. We plan the pages and features together.

3. I build, test and deliver your app.


Please message me before ordering so we can agree on the scope.


Native Spanish speaker; I communicate in English with the help of translation tools.
