  1. Building advanced UI Frameworks to be the best payments SDK in the world:

    Juspay’s ‘Hyper SDK’, a micro app platform enables native app experiences using JavasScript/PureScript. It is a well architected system that enables isolated and parallel deployment of UI features rapidly; using dynamic over-the-air updates.
