It sounds like you only want to build the frontend yourselves? You could take a look at Cube[1] which will probably work fine as a backend for your in-app reporting.
Cube is “headless BI”, which means you still have your own widgets at the front lend, and existing DB at the backend, and Cube sits in the middle helping you combine/filter/group/stat across your tables and other data sources.
