Microsoft Teams Custom Task & Time Tracker

We are looking for a skilled developer to create a custom app for Microsoft Teams that enhances task management with robust time-tracking capabilities. The app must be built using the Microsoft Teams Developer Platform and operate entirely within Teams for seamless integration and user experience. Ideally, the app will work alongside the existing Planner app in Teams. If integration is not feasible, the app must replicate Planner’s features while adding time-tracking functionality and other enhancements.
