About the project

The project involves the development and customization of a mobile banking platform delivered in a Software-as-a-Service (SaaS) model. The core product is a whitelabel mobile wallet solution offering secure, user-friendly, and feature-rich banking experiences out-of-the-box.

The project includes tailored customizations for individual clients. This includes the development of plugins and add-ons to extend core functionality, integration of standalone services via API, and customization of mobile applications to meet specific branding, UX, and functional requirements.

The architecture is modular, scalable, and API-first, enabling rapid deployment and adaptability to evolving market needs. The goal is to deliver a flexible mobile wallet solution that supports fast go-to-market strategies while allowing deep client-specific personalization.
