User Interface Design

Android & iOS

Trustica is an enterprise solution for secure communication between trusted entities. The initial proof of concept for the technology is a mobile app with secure and private VoIP, private messaging, with anonymous deep-privacy protection.

My role was to work with C-suite stakeholders, lead the UI design effort, and guide developers to create the final product.


Starting with the Android app, I created sketches and wireframes based on high-level requirements. With Adobe XD and Sketch, I quickly created mid-fidelity mockups early on in the process. This enabled me to get a much higher rate of engagement and useful feedback from stakeholders.

Based on client feedback, I moved forward with a clean, modern design that reflects the colors and graphics of the Trustica branding. This design direction ensured consistency and unity across multiple platforms and products.

Modular Design System

The Trustica Mobile Design System was built to allow for scalability, so various components and assets will complement each other and render well on various screen sizes. Elements of this design system are utilized in the Trustica Management System web app, providing consistent user experience and conventions across both platforms.

A selection of elements from the design system are sampled below.

Developer Support

Design specs and assets were provided to developers along with ongoing support and guidance during the implementation processes.

Android Design

Mockups and renderings of the Trustica mobile app were designed to aid marketing and promotional efforts worldwide.

Android & iOS Design Conventions

As the android development progressed, we began work on the iOS app. Utilizing Apple’s human interface guidelines was crucial to adapt the Android interface while maintaining Trustica brand identity.

iOS Design

In addition to designing the Android application, I owned the design process for iOS and guided a team of developers in the creation of the app.
