Funds are collected from individual shoppers checking out from multiple shops at once and dispersed to vendors as a bulk payout. The vendors were also able to accept/reject upcoming orders and make refunds through the system as well. Each outlet required individual shop front within the system and had to maintain product collections. This required the database (MongoDB) to scale fast and also support fast product search. To optimise performance and to adhere to shopping mall’s customization requests the monolothic backend architecture was transformed to a microservices architecture. React Hybrid was used to build the App to increase the speed to go to market as oppose to using a native technology. Intuitive user experience design pairing with high quality frontend architecture was essential because of the complexities from creating a virtual mall experience compared to a regular eCommerce app. Cart which enables users to checkout from multiple shops in one click, category and product search from multiple outlets, chat, creative product pages had to be creatively designed and also frontend session data had to be cleverly managed to increase usability. Consistent availability had to be ensured (aws deployment set up) as its public shopping app and a fallout would result in a loss of thousands of users. Potential concurrency issues had to managed to avoid managing product availability and order processing.

The innovative concept of creating a shoppable virtual mall was intelligently architectured and implemented accounting to scalability, concurrency, usability and security by world-class engineers.
