• Experience with server-side rendering or meta-frameworks (e.g., Next.js, Remix).

• Knowledge of micro-frontend architecture patterns.

• Background in web accessibility standards (WCAG 2.1) and assistive technology testing.

• Exposure to CI/CD pipelines and DevOps practices for frontend deployments.

• Experience with animation libraries (e.g., Framer Motion) or data visualization tools (e.g., D3.js, Recharts).

What Success Looks Like
