Education That Engages and Adapts
Built comprehensive education ecosystems combining student marketplace engagement with institution-grade LMS featuring adaptive assessments, integrity enforcement, and parent visibility.
The Challenge
Education platforms require balancing student engagement with academic integrity, personalized learning with scalability, and institutional control with user experience. The challenge was building a system that serves students, teachers, parents, and administrators while maintaining strict data isolation and compliance.
Solution
The solution delivered two complementary platforms: CampusCart for student community and marketplace engagement with AI-assisted learning, and a multi-tenant LMS with adaptive assessments, integrity enforcement, and comprehensive analytics—all with per-tenant isolation and FERPA alignment.
The Impact
The platform achieved 27% student retention increase, reduced exam integrity violations to under 5 per 1000 attempts, enabled 62% parent portal engagement, and delivered adaptive learning that increased practice completion by 38%.
Key Challenges
Real-time collaboration without consistency drift
Assessment integrity with anti-window-switch enforcement
Adaptive learning with personalized practice generation
Scalable multi-tenancy with strict data isolation
AI integration with safety guardrails and rate controls
Parent portal with privacy-aligned scope limiting
