Building Modern Mobile Banking Apps

Architecture, multiplatform delivery and security at scale

In this webinar, Etnetera Flow and Wultra will share how modern mobile banking products are built to scale, stay maintainable over time, and protect users across the full banking journey.

The session is intended for mobile, architecture, and security leaders in banks and financial institutions.

Mobile apps built for the long run

A mobile banking app is never really finished. It evolves across teams, features, and years of operation. We will show how architecture, team structure, onboarding, and quality controls help keep the product consistent as the organisation around it changes.

Delivery without losing control

Speed alone is often not the main challenge. The harder part is keeping delivery predictable without letting quality drift. We will discuss how modular architecture, Kotlin Multiplatform, clear team roles, and automated quality checks help teams work on the same product without losing control.

Security across the banking journey

Security needs to work together with architecture, delivery, and user experience from the start. We will show how banks can protect users across onboarding, login, payments, 3D Secure and web banking, and why the most effective mobile security often remains invisible to the user.

Real Attack Scenario

We will walk through a real investment scam seen across Europe and show how a multi-step attack moves across the banking journey, and where mobile security can stop it before money is lost.
