M365/ PowerApps Project Development Support

I run an M365 Consultancy and have multiple projects on the go that need extra support as I have more projects in the pipeline. Each project is a PowerApps build, some also include an element of PowerBI. I'm looking for a competent developer with broad experience across projects who is confident in all aspects of the PowerApps build process. I am particularly interested in anyone with experience of contemporary design work in the look & feel of a PowerApp but most importantly a good grounding in all aspects of working with a diverse range of data sources including but not limited to SharePoint, Dataverse, Excel, OneDrive for Business, SQL etc.
