Security & Compliance
• Collaborate on security measures, ensuring safe handling of user data and compliance
with best practices.
• Define secure patterns for file handling and API integrations.
Data & Observability
• Capture user interactions and performance metrics.
• Use metrics to prioritize refactors and ensure system reliability.
Collaboration & Process
• Drive cross-team initiatives and contribute to shared code repositories.
• Guide migration or consolidation efforts to ensure a cohesive design system.
Innovation
• Evaluate and implement emerging frontend patterns and technologies.
