Custom Digital Onboarding System

I need a complete onboarding system built from the ground up. The core purpose is to welcome, educate, and guide newcomers through a structured flow, whether they are employees, clients, or general users. At this stage the platform is still open—web, mobile, or even a lightweight desktop build could work—so I’m happy to weigh your recommendation once you understand the requirements and audience size.

Key capabilities I already have in mind include secure account creation, the ability to monitor progress through each step, and an engaging tutorial experience that can mix text, video, and quick-check quizzes. If there are smarter ways to keep people motivated or to surface analytics for admins, please propose them; I’m not locked into any single feature set yet.

What I need from you:
• A clear technical plan outlining your chosen tech stack, data model, and any third-party services
• UI/UX wireframes that show the complete flow from first visit to full completion
• A working, tested build with admin controls, plus deployment instructions or an automated script
• Brief documentation so my internal team can extend or localise the system later

I’ll review milestones based on tangible progress—initial architecture, clickable prototype, beta launch, then final hand-off—so be ready to demonstrate visible results at each stage. If you’ve shipped similar onboarding or learning portals before, links or screenshots will help me see how you tackle usability and scalability challenges.

Let me know which framework or language you believe suits this best, how long each milestone would take, and any assumptions you need me to confirm before we start.
