I'd like to work on this issue because analytics and reporting tools are essential for helping agents understand their performance and activity on the platform. A well-designed analytics dashboard can improve transparency, provide actionable insights, and enhance the overall agent experience.

I have experience building full-stack applications with React, TypeScript, Node.js, and data visualization libraries. I'm comfortable designing analytics APIs, implementing secure authentication flows, aggregating time-series metrics, and creating responsive dashboard components with charts and filtering capabilities. I can build the analytics endpoint, add date-range reporting, integrate agent signature verification, and create a clear, user-friendly dashboard that presents earnings and performance metrics effectively.
