Bruna Balves contributed to the totvs/winthor-smart-hub-layouts repository by focusing on front-end development tasks that improved both stability and data accuracy. She addressed broken navigation URLs, ensuring users could reliably access different layouts, and enhanced the product information display by refining how product data is fetched and rendered. Her work involved careful branch alignment and risk management to support smoother releases. Using JavaScript and HTML, Bruna fixed two bugs and delivered one new feature within a month, demonstrating a methodical approach to code maintenance and user experience improvements while maintaining a clear focus on navigation reliability and data integrity.
