UBS Design System
A design framework used by dozens of teams around the world with various front-end technologies. It provides a unified approach to building digital products and services, with a framework-agnostic design system compatible with Vanilla JavaScript and a React version. The system is designed based on accessibility and usability principles. Also, it is scalable and modular, enabling teams to customize and extend the components according to their specific needs.

Vievu offers a body camera solution specifically designed for law enforcement agencies. In addition, It is an on-site system that empowers law enforcement agencies with the flexibility to manage their IT and video storage environments.

While working on the solution, I introduced a new feature that enables users to create face masks for their videos directly in the browser. Furthermore, I added the ability to create bookmarks and subtitles for specific video parts.
