Hi,
Reading your project description about need of a developer that can help create the visualizations that will be able to handle multiple data sources and also use Power BI, Dash, Tableau or some other tool used to create a dashboard,makes me feel like you have me in mind when creating the project. I have all it takes to deliver.
Rather than fill this proposal with a list of qualifications, I want to complete a part of this project as a proof of concept before you award this project. This is so that you can be confident of the hands you will entrust this task. If you are satisfied with the result, you can go ahead and award the project.
I’d love to discuss more on what would make this project a success for you. Can we have a quick chat?
Thanks for your time
