Custom Cross-Platform Data Dashboard Development

I am looking for a skilled developer to build a custom dashboard that can be accessed via both mobile and desktop. The dashboard will need to pull data from various sources and provide clear, comprehensive analytics. The key requirements are as follows:

1. Data Integration:
API Integration: The dashboard must connect to my advertising accounts (Google Ads, Snapchat Ads, TikTok Ads, Twitter Ads, Pinterest Ads, Meta Ads) and pull data through APIs.
Excel Integration: Ability to import and process data from Excel files.
Database Storage: All collected data should be stored in a database for future access and historical analysis.
2. Data Analysis & Reporting:
The dashboard should analyze data and generate reports for the following periods:
Daily
Weekly
Monthly
Quarterly
Annually
The reporting should be customizable to view metrics across different platforms and timeframes.
3. User Interface & Experience (UI/UX):
The dashboard should be easy to navigate and visually appealing, providing a seamless experience across both mobile and desktop devices.
A clean, intuitive design that allows me to quickly access insights and make data-driven decisions.
4. Additional Considerations:
The dashboard should support user-friendly visualizations like charts, graphs, and tables.
Ideally, the developer should have experience in working with advertising APIs, databases, data visualization tools, and mobile-responsive design.
