Secure messaging app

Mobile security and device management solution on iOS and Android for corporations that need to manage their internal team and maintain internal information integrity. With the device management, the application enables internals to communicate through a secured and encrypted channel with the assurance that their corporate information transferred (whether it be messages, files, photos, and recordings) is protected from any malicious attacks.

My role

I work collaboratively with our Developers to guide user experience design throughout the planning and development lifecycle for our mobile platforms and management system. More about me.

Different platform design languages

Each screen is designed with which a user interacts and ensuring that the user interface visually communicates the path that my user experience work was laid out.

The navigation within the application needs to feel appropriate with customized icons on each platform. I craft icons, controls, and visual elements, making use of suitable typography.

The primary application colours are neutralized to allow the sparse use of the primary blue and content to take center stage. Each area of the app is branded with a colour not only for aesthetics, but also for functional experience.
