UNICOS was born at CERN in early 2001 with the development of the LHC cryogenics control system. It deals with the two upper layers of a classical control system: Supervision and Control. UNICOS proposes a method to design and develop the control application which will run in commercial off-the-shelf products (e.g. SCADA and PLCs).
The first step in the redesign process is to align panels with the UNICOS’s updated branding guidelines. This involves incorporating consistent visual elements such as colors, fonts, and icons, ensuring that the panel not only functions well but also reinforces the brand's identity.

Since WINCC OA is not a design tool hence, to overcome the limitations of WINCC OA and to implement the necessary visual enhancements, QT CSS, a style sheet language tailored for QT applications was used.

Repeated this same process for over 300 panels.
Analysis → Design → Development
My role primarily involves addressing JIRA issues—typically minor bugs that were overlooked or overwritten during the redesign—and implementing UI enhancements based on the recommended changes, as illustrated in following screenshots.
Problems reported are both:
i- Technical - Functionality oriented
ii- Design Oriented
I also implementing dark mode for UNICOS, allowing users to seamlessly switch between light and dark modes via the HMI. This process includes designing a color database, theme specific icons, and optimizing the code for a smooth user experience.
