Our Approach
Tech Ventura’s team started with a highly focused, 2 weeks of discovery engagement with the client to identify their business goals and mapping them into a technology blueprint. A solution architecture was then derived using this technology blueprint, which then converted into an Agile based technical delivery plan.
AWS Cloud platform was selected to deploy the solution backend, which was built as AWS Lamba based Microservices and exposed as REST APIs. An integration layer was developed to connect to the Telco Mobile Wallet systems combining several middleware components to achieve a robust solution.
An Android-based mobile app was developed to run inside the POS device, which carried out all the payment transactions. An intuitive user interface made the POS vendor’s life much easier during rush hours. The offline capability was built to handle several business cases for vendors who are on the run and who visit areas without network coverage. The synchronization engine was designed to seamlessly push and pull data between the device and the platform.
