Abstract Micro-Learning SaaS

We are seeking an experienced Laravel developer/team to build a highly scalable, multi-tenant B2B SaaS core framework. We can Provide Logo and Website Design mockup. The application functions as an abstract, sequential learning management engine where administrators can structure content pathways for individual users.To maximize development efficiency, the project must utilize Filament PHP for the administrative backend and Tailwind UI/CSS for the user interface.Note: A detailed Non-Disclosure Agreement (NDA) must be signed before the final database schema, branding guidelines, and exact target-market feature extensions are revealed.Core Architecture & Technical StackBackend: Laravel 11+Database: PostgreSQL or MySQLAdmin Panel: Filament PHP (Multi-tenant structure)Frontend UI: Tailwind CSS / Tailwind UI (Application UI layouts)Media Integration: Secure Video Streaming via API (Vimeo or Mux)Infrastructure: European Cloud Hosting (Hetzner Cloud)Abstract Module Requirements for the MVP1. Multi-Tenant Core ArchitectureStandard multi-tenant database isolation.Tenant Domain Mapping: System must allow individual tenants to map their sub-account to a custom domain (e.g., ://tenantdomain.com) and apply a basic custom CSS stylesheet (logo, primary/secondary colors).2. Tenant Admin Console (Built with Filament PHP)Sequential Path Builder: An interface allowing tenant admins to group content blocks sequentially (Step 1 → Step 2 → Step 3). Each step contains an embedded video player, an optional text block, and a verification quiz.User Management & Analytics Dashboard: A data grid showing a list of users mapped to that tenant, their progress metrics (0-100%), and quiz score histories.Dynamic Quiz Builder: A tool to create multiple-choice verification questions with configurable passing thresholds (e.g., X out of Y correct answers required to advance).3. End-User Interface (Built with Tailwind UI)Strict Linear Progression Engine: A minimalist, distraction-free environment for the user.Player Control Restriction: Custom JavaScript integration with the video API to completely disable timeline scrubbing/fast-forwarding. The user must watch the media track completely before the framework triggers the database state change to unlock the subsequent step.Quiz Interface: Interactive form layout triggering immediate evaluation. Failing to meet the score threshold locks further navigation.4. Automated Document Generation EngineVerification PDF Generator: Upon a user successfully finishing a defined pathway, the backend must instantly compile a secure, unmodifiable PDF document detailing user metrics, completion timestamp, score logs, and tenant metadata.RFQ Submission Requirements:Please provide a rough estimate of total development hours, split into:Multi-tenancy & Backend CoreFilament Admin CustomizationFrontend UI IntegrationVideo API and PDF Generation
