We built one Vue 2 single-page app with a Laravel web-services layer. The subdomain selects the partner from a config that sets its title, colours, logo, alarm-centre phone, back-office ID, available flows and verification mode: national ID number (PESEL), policy number or user name. Step-by-step wizards cover home repairs with photos, medical symptoms and roadside problems, and a separate view shows case status by number. The API handles image uploads and CORS and runs on nginx or IIS. I designed the architecture and led the backend.
