The Laravel backend exposes separate Swagger-documented APIs for administrators, local organisations, partner companies and members, consumed by a Vue 2 frontend with Vuex and i18n. Providers publish services with price lists; orders, invoices, ratings and donations flow through Stripe with webhooks, and documents are generated as PDF, Word and Excel. Support chat runs on laravel-websockets with rooms linked to orders. I designed the architecture and built the payment flows; the admin covers order statuses, user verification, granular roles, open issues and a CMS.
