Client project
The Muallimah
An online English school for women: video courses, a book and merch shop, certificates and teacher chat on one platform.

The problem
The client had a large YouTube and Telegram audience, but course sales, lessons and student communication were scattered across different services. They needed a platform of their own to bring it all together.
What we built
- Courses, modules and lessons, with Zoom links for live classes
- Video uploaded straight to YouTube or streamed over HLS from our own server
- Exercises, quizzes and homework reviewed by teachers
- A PDF certificate once 80% of lessons are watched
- In-browser book reader and a branded merch shop
- Payments via Payme and Click, promo codes and instalments
- Real-time chat: direct messages, course groups and support
- Student, teacher, admin and superadmin roles, plus a teacher hiring pipeline
- Blog, stories and shorts in Uzbek, Russian and English
