About the Client

Smarta is a technology provider for mobile virtual network operators (MVNOs). The app allows telecom brands to offer their users a digital-first experience — enabling them to manage their accounts, track spending, and purchase additional services directly from their phones.

Main request

The client wanted to build a white-label solution that any operator could adopt and customize with its own branding, pricing plans, and APIs. The main challenges were: supporting multiple telecom APIs with varying logic and data structures, ensuring the app could be quickly rebranded and redeployed, and designing a modular backend that allowed real-time balance and plan updates.

What we did

Designed a multi-tenant architecture to support several telecom brands under one backend with dynamic configuration layer

Built a cross-platform Flutter app with modern, clean UI adaptable to any brand identity with reusable components

Implemented modules for balance top-up, plan selection and switching, usage analytics, notifications and support chat

Developed Node.js backend for user management, transaction logging, and operator API orchestration with retry logic

Built internal tooling for generating branded app builds and automated build scripts for iOS and Android deployment

Problem solving

The biggest challenge was building a single app that feels native to each operator. We solved this through a layered configuration system that separates branding, data endpoints, and logic — allowing new operator launches without code duplication or complex re-deployments.

Complex telecom API integrations

Slow release cycle
