Solution Architecture

• React Native mobile app with modular screens (catalog → lesson → quiz → certificate).


• PHP backend API for auth, content, enrollments, transactions, and webhooks.


• Next.js for marketing site + secure admin panel (role-based access).


• Optimized media pipeline for videos, PDFs, and interactive labs.

Key Features (Phase-1)

• Course catalog with tags, difficulty levels, and prerequisites.


• Learner dashboard: progress, streaks, saved items, recent activity.


• Assessments & certificates with verifiable IDs.


• Secure checkout, receipts, promo codes, and invoice emails.


• Announcements & push-ready notifications (roadmap).

Design System

A clean, high-contrast UI with dark-mode parity. Components follow a compact density for mobile, with larger tap targets and clear typographic hierarchy for long-form reading.

Accessibility & Localization

WCAG-minded contrasts, semantic structure, and scalable text. The content system anticipates multi-language support and RTL layouts in future phases.

Security

• Token-based auth, rate limiting, and audit logs for critical actions.


• Hardened file access for course assets; signed URLs for media.


• Payment integrations via PCI-compliant gateways (server-side validation).

Performance & Scale

• Edge-cached content delivery and lazy loading for media-heavy lessons.


• Background jobs for certificate generation, email, and analytics ingestion.


• Telemetry hooks to measure completion rates and funnel drop-offs.
