Android App & Web Dashboard Development

I'm seeking an experienced Android app developer to create an app that collects and logs call data. Additionally, I need a web developer to design a dashboard displaying this data.

The mobile app should:
- Collect call logs
- Record call durations
- Log call outcomes (missed, retried)

The web dashboard should visualize the data with:
- Graphs and charts
- Tables and lists
- Summary widgets

Users should be able to filter the data by:
- Date range
- Individual user
- Call type (missed, retried)

Ideal skills and experience:
- Proficiency in Android app development
- Experience with web dashboard design
- Strong data visualization skills
- Knowledge of backend integration for real-time data sync
