Day 74: User Management API - Building Production-Grade User Administration
What We’re Building Today
Today we’re building the API backbone of user administration—the same patterns that power GitHub’s user management handling 100M+ users, Slack’s team coordination serving 20M+ daily active users, and Auth0’s identity platform processing 2.5B+ login transactions monthly. You’ll create:
User Management Endpoints: Full CRUD operations with intelligent caching
Team Management API: Multi-tenancy support with role propagation
Permission Management: Dynamic permission assignment and validation
User Activity API: Real-time activity tracking with aggregation
Advanced Search & Filtering: Elasticsearch-style queries with sub-50ms responses
