Optimize application performance, reliability, and overall user experience.

Use AI-assisted development tools like Copilot, Cursor, or Claude Code as part of your daily workflow.

Hands-on experience with Tailwind CSS and modern component libraries such as shadcn/ui, Radix UI, or similar design systems.

Proven experience building real-time or streaming UIs.

Strong understanding of client-side state management in complex applications.

Comfortable shipping production-ready frontend features with attention to quality and detail.

Strong experience using AI-assisted engineering tools as a force multiplier in day-to-day development.


Nice to Have
