About this gig

If your app has outgrown Google Sheets, logins keep breaking or users can see data they should not, the fix is usually a proper backend. I set up Firebase and connect it to FlutterFlow, Bubble, Adalo or Glide so your users, data and notifications run from one reliable place.


What you end up with:

  • Users who sign in with email, Google or Apple without errors
  • A Firestore database structured to stay fast as you grow
  • Security rules that keep each user's data private
  • Push notifications that actually reach phones
  • Cloud Functions for custom logic on Premium


How I connect it:

  • FlutterFlow: native Firebase setup
  • Bubble: API Connector and plugins
  • Adalo: External Collections through the API
  • Glide: API calls, webhooks and syncing through n8n or Make


Most of my week goes into n8n automations and leading a website team, so connecting systems that were never built to talk to each other is familiar work for me.


I can also build a Glide admin panel on top of your data, so your team manages everything from one dashboard.


Need a specific fix instead of a full setup? Message me the issue and I will quote you before you order.

Hi, I'm Karl. I build web and mobile apps with Bubble, Adalo and FlutterFlow, and set up Firebase backends that hold up as your users grow. I lead a website team at a digital agency and build n8n automations, so I plan every app around how your business actually runs, from payments to the tools you already use. Founders and small businesses come to me for MVPs, client portals, booking apps and internal tools. You own everything I build, and you get a walkthrough video at handover. Message me with your idea and I'll suggest the best way to build it.
