●  Aggregator portal for a company named ringo, which allows for the purchase of airtime and Data by different End Users. The portal serves as an intermediary between Billers who have Airtime and Data to sell and End Users who are in need of either of both products. The Portal was designed for cases when a biller is down, at this point, the active Biller switches to the next biller who has the product in need at that moment.
