Challenge
The client approached ZONE3000 with several critical issues affecting their growth:
Technical debt: Legacy PHP codebase with custom CMS, causing frequent outages and slow feature development.
Scalability issues: System crashes during peak usage times, particularly impacting international users.
Limited mobile support: Poorly optimized mobile experience, leading to high bounce rates (>60%) on smartphones.
Content management: Inefficient process for updating course materials across multiple languages.
User retention: Low completion rates (<20%) for courses due to lack of engagement features.
Solution
ZONE3000 proposed and implemented a comprehensive 6-month redesign:
Backend overhaul
Migrated from custom PHP to Node.js with Express, using MongoDB for flexible content storage.
Microservices architecture
Developed discrete services for authentication, content delivery, and user progress tracking.
Progressive web app (PWA)
Built a responsive frontend using React.js, enabling offline mode for vocabulary practice.
Content API
Created a GraphQL API for efficient, language-agnostic content updates and third-party integrations.
Gamification
Implemented a points system, leaderboards, and daily streak tracking to boost engagement.
Technology used
Backend: Node.js, Express, MongoDB.
Frontend: React.js, Redux, Service Workers.
API: GraphQL with Apollo Server.
DevOps: Docker, Kubernetes on AWS EKS.
Monitoring: ELK Stack (Elasticsearch, Logstash, Kibana).
