Hello,
I'm a qualified AWS Solutions Architect and DevOps Engineer( Professional ) and I run a small AWS Select Consultancy in Cardiff, UK.
I am perhaps not exactly what you are looking for but I've done a lot of work with Quicksight including the gathering of data, formatting it for analysis and storing it in various engines such as RDS, S3 and Athena. I've run projects in the UK for reporting on NHS projects and data for the restaurant and pub market. The reports used all different type of charts along with controls, filters, parameters, calculated fields etc...
I've done many integrations of Quicksight into web pages using React, Cognito and IAM to share analytics embedded in an online portal.
As I said, I am not sure this is exactly what you are looking for but perhaps I do have some experience and skills that could help you.
Many Thanks
Mark
