• Implement predictable state structures and side-effect management patterns using Redux or similar state-management libraries
• Ensure smooth communication and data flow across microfrontends, web components, and UI modules
• Build inclusive user interfaces aligned with WCAG and WAI-ARIA standards, using accessibility testing tools where needed
• Optimize frontend code, rendering performance, first-load time, runtime performance, and perceived responsiveness
• Identify and address layout shifts, memory issues, rendering bottlenecks, and browser/device compatibility problems
• Create and maintain unit, integration, and end-to-end tests; use modern debugging tools to troubleshoot issues efficiently
• Collaborate closely with backend developers, designers, product owners, and QA engineers in cross-functional squads
