Full Stack, Paddy Wack, Web App. Who am I looking for?

Folks, I'm having trouble narrowing down the title of who I need to bring my product to market. Can you help?

I'm probably using the wrong technical terms, so bear with me. (And I appreciate any corrections)

We will be getting in transaction data from multiple payment processors (think Stripe, Square, etc). Need to build a bridge so we can keep calling in to the provider to get new data. We want to store it in some common data model so we can run the same reports and analytics regardless of which provider it comes from.

We want clients to access the reporting by a dashboard that will update as new information becomes available.
