Development of SaaS web-app in Webflow

The web-app is a SaaS web-app, containing a database to almacenate information about actors and actresses and their respective agencies managing them. It would have around 30 pages, 20+ different features, an Admin Panel, and two more different type of profiles (For Administrators and Agencies). The current website is based on Webflow (CMS package) but the development of the web-app can be done inside or outside webflow depending of the most convenient option.
