Finefoods Ant Design Admin Panel - refin...

Hi everyone, I am new to refine admin framework. My background from SPA react js and Node middleware write in typescript. I am looking for a right tool to develop Privilege Account Review and Management for company. Does refine admin support my existing restful api? And does it allow me to build custom page? So far my reference is based on Finefoods https://example.admin.refine.dev/
