Grocery & Fruits Delivery App Development -- 2

I'm in need of a skilled mobile app developer who can create a fast and efficient grocery and fruits delivery app for both iOS and Android. This app should include:

- A robust search engine that can correct spelling mistakes.
- Well-structured subcategories and categories for easy navigation.

Additionally, the app needs to support user authentication and account management through email and password.

Please note, GST invoice generation is not a requirement, but I will need an invoice with a GST number for transparency with our funding partners.

Ideal skills for this project include:

- Proficiency in iOS and Android app development.
- Experience with creating search engines within apps.
- Knowledge of user authentication and account management systems.
- Ability to generate invoices within the app.

Thank you.
