Basic Auth, API Keys, JWT, OAuth 2.0 — with real request traces.
WebSockets, SSE, pub/sub patterns for chat, dashboards, IoT.
REST, GraphQL, JSON-RPC, gRPC — when to use which, with trade-offs.
Oracle Cloud, nginx, systemd, HTTPS, CI/CD — from laptop to production.
Python (FastAPI, Flask), async I/O, testing, clean architecture.
Fine-grained access control models including RBAC, ABAC, ReBAC, and Policy-Based Access Control (PBAC).
