Have a nice day, I have deep experience on Tableau and QlikView development, data-analysis as well as hybrid mobile application development (Ionic framework), backend/frontend web application (Laravel framework) or database using and administration (MySQL, MS-SQL).
For Tableau or QlikView projects my rate is 20€/hour (resp.$22), but finally depends on project. I think that pretty fair for quality of work.
I can communicate through Webex or Skype. Possible work on daily basis.
