Wisecool

Enterprise Educational Platform - 14 Microservices Architecture

⚠️Le Problème

Educational institutions needed an enterprise-grade platform to digitally transform education. Requirements included: programming course support with live code editors, real-time collaboration, multi-language support (Arabic RTL critical), mobile-first design, offline capabilities, video conferencing, enterprise messaging, comprehensive SEO for student acquisition, and production-level security with zero vulnerabilities.

✓Ma Solution

Architected a 14-microservice ecosystem: wisecool-app (Next.js 16 with 8 Monaco code editors), wisecool-api (Django 5.2 with 40+ apps), wisecool-messaging (Django Channels + WebSocket), wisecool-mobile (React Native), wisecool-desktop (Electron), wisecool-admin, wisecool-instructor, wisecool-library, wisecool-internship, wisecool-editions-api, wisecool-ums, wisecool-landing (10K+ SEO keywords), wisecool-status. Features include 8 specialized code editors, enterprise messaging with 25+ features, and production-ready security.
