Multitenancy

System spans across multiple universities, isolating data via scoped identifiers in every database query.

Async Tasks

Redis powers offline job processing for emails and notifications, keeping the main API thread responsive.

Connection Pool

SQLAlchemy async engine manages a high-performance database connection pool for heavy concurrent traffic.

S3 Fallback

Intelligent file handling service checks AWS connectivity and falls back to local storage automatically.
