21 Günde Marka is a fully custom education platform built from scratch to enforce consistency and completion discipline. Users can review the 21-day program before purchase, then continue with secure Iyzico payment, auto account creation, and day-by-day progression. Each day follows a mandatory sequence (video, PDF, quiz), with anti-skip controls, minimum quiz score rules, and countdown-based unlocking at 23:59. The system also includes automated personalized certificate generation, queue-based email workflows, Vimeo private video controls, and a scalable Laravel + PostgreSQL + Redis backend on Ubuntu VPS.
