Finish and eCommerce Application

A developer was hired to create an mobile marketplace, which includes:
i) A customer application
ii) A store application
iii) A driver application

We started to integrate with payment providers but the developer was unable to finish due to another commitment.

I am looking for someone to:

-Complete Payment integrations with Airtel Money and Cellulant

- Fix issue with Customer Application os it loads

- Update Driver/Rider App so that Drivers can sign up as employees of a delivery company. Payments will be made to the delivery company who can then distribute among the drivers. So we need to ensure that the app is keeping track of who made which deliveries.

- Ensure that app is tracking sales and can easily make reports so that we can easily pay drivers and stores, AND so that we can record payments that we have made.

- Finish back end
