A new financial-services company in Canada needed a mobile app that could grow into full banking features without a rewrite, and that treated security as a starting condition, not a later phase.

Structure first. Before any feature screen, I defined the layers, boundaries and security model that every future module would plug into.

I designed and built the core of the mobile app: a layered architecture ready for complex banking modules, robust authentication flows, and biometric sign-in with fingerprint and face for fast, secure access. Sensitive data was protected by default from the first commit.

The client got a secure, scalable base to build banking features on, instead of a prototype to throw away.
