WealthGooru is a secure digital learning platform delivering professional-grade stock market trading and financial literacy courses to 5,000+ students across India. Designed and developed solo as a freelance project, from UI/UX design through frontend development. The platform faced three core problems: fragmented content delivery, error-prone manual referral tracking, and premium content vulnerable to redistribution. The solution: a dual-dashboard architecture — a student hub for courses, curriculum progress, and real-time referral earnings, plus an admin backbone for content, student records, and commission payouts. A custom 3-level referral commission engine automatically tracks relationships, calculates commissions, and enforces distribution caps with zero manual intervention. A multi-layered content protection framework delivers video via streaming only (no downloads or hotlinking), enforces multi-device access controls and session monitoring against credential sharing, and serves PDFs through a controlled layer limiting extraction. Results: scalable infrastructure accommodating rapid user growth without proportional overhead, a transparent referral network with real-time commission visibility, and protected course IP. Key outcomes: automated 3-level referral engine, 5,000+ users supported, streaming-only delivery, centralized course and user management
