I will build a custom offline first web app with react and firebase


About this gig
Looking for a reliable web app that actually works even when the internet doesn't?
I build custom web applications using React, TypeScript, and Firebase, with a focus on offline-first architecture. That means your app keeps working through spotty internet, syncing automatically once connection returns something most developers don't design for.
What I build:
- Point-of-sale (POS) systems for retail and distribution businesses
- Inventory and business management tools
- Booking/appointment systems for clinics and service businesses
- Custom dashboards and admin panels
- Bilingual apps with full French and Arabic (RTL) support
I've already delivered real, working apps for a veterinary clinic, a poultry farm business, retail shops, and a cafeteria not templates, custom builds solving real business problems.
Why work with me:
Offline-first architecture your app doesn't break when the connection does
Bilingual/RTL support built in, not bolted on
Clear communication throughout the project
End-to-end delivery: from understanding your process to deployment
Send me a message with what you're trying to build, and I'll tell you honestly whether it's a good fit and how I'd approach it.

FAQ
What if my business has a slow or unreliable internet connection?
That's actually my specialty. I build apps offline-first, so they keep working without internet and sync automatically once you're back online.
What information do you need to get started?
A description of your business process, what problems you're trying to solve, and any existing tools you use (spreadsheets, paper, another app). I'll ask follow-up questions to scope it properly.
Can you build a POS (point-of-sale) system for my shop?
Yes — I've built POS systems for retail, distribution, and cosmetics shops, including offline sales tracking and inventory management.
What happens after delivery? Do you offer support?
Yes, I offer post-delivery support and can discuss an ongoing maintenance arrangement if you need updates or changes over time.
