• Dashboard/SaaS application development
• Experience with complex multi-role applications
• Experience with academic, publishing, research or workflow-based platforms

What We Are Looking For

We are looking for someone who can understand an existing application before changing it.

Strong attention to:

• UI quality
• UX
• Performance
• Clean architecture
• Reusable components
• Security
• Cross-browser compatibility
• Maintainability

is required.

Important

• Existing backend and database should be reused wherever possible.
