Thulani Sikhosana worked on the shesha-io/shesha-framework repository, focusing on standardizing terminology within the Form Designer UI. He replaced all instances of 'Widget' with 'Component' across the main area and toolbox, using React and TypeScript to ensure consistent language throughout the interface. This change improved design-system alignment and reduced potential confusion for developers, particularly those onboarding to the project. By addressing terminology at the code and UI level, Thulani laid the foundation for broader standardization efforts across modules. His work demonstrated attention to detail in front end development and contributed to a more cohesive developer experience.
