• Ensure accessibility, responsiveness, and adherence to modern UI best practices.
• Optimize performance through code splitting, lazy loading, and efficient rendering strategies.
• Implement secure front end patterns, including dependency hygiene, API input validation, and token handling.
• Review and refactor front end code to ensure maintainability and consistent patterns.
• Mentor team members on React, TypeScript, testing strategies, and SPA architecture.

Education and Background

• Understanding of accessibility and compliance standards common in government systems.
• Experience deploying front end applications to AWS services such as S3, CloudFront, API Gateway, and Cognito.
• Strong troubleshooting skills in UI performance, rendering, and cross browser compatibility.
• Self directed with the ability to own features from concept to production.
