PowerBI Dashboard & Reports

I'm looking for a seasoned PowerBI specialist who can integrate a range of data sources into two neat, insightful dashboards and reports. Here's what I need:

- Integration: there are two unrelated datasets, both in .csv file format, the larger dataset is already loaded into PowerBI and few relationships and basic graphs were already created - you would continue on where I ended. Second data set will have to be loaded into PowerBI as well but it is independent from first one and contain small amount of data.
- Visualization: I don't have any specific requirements regarding visualizations or charts but I will provide examples and details about what I want to visualize. I expect you to have the expertise to determine and create the most meaningful data presentations for the dashboard and reports that will be on advanced level.
- Metric Display: I will provide specific metrics once freelancer will be chosen.

Skills and Experience needed:
- Proven experience with PowerBI.
- Ability to determine effective data visualizations without explicit guidance.
- Experience in establishing critical KPIs based on available data.
- Excellent analytical skills and attention to detail.
- Mastery of Excel and SQL databases.
