Design and implement REST APIs with OpenAPI/Swagger (versioning, pagination, consistent error model).

Develop GraphQL APIs in Python (schema design, resolvers, batching, caching).

Build real-time features with WebSockets (FastAPI/Starlette, Django Channels) for chat, presence, live updates.

Implement event-driven services and message consumers/producers (Kafka/RabbitMQ/SQS).

Create background jobs and schedulers (Celery/RQ/Arq; queues, retries, backoff, idempotency).

Implement authentication and authorization in Python services (OAuth2/OIDC, JWT, RBAC, mTLS where needed).

Optimize Python performance (profiling, async I/O tuning, memory leaks, CPU hotspots).

Implement caching strategies (Redis, in-memory, cache invalidation patterns).

Create observability for Python services (structured logging, OpenTelemetry tracing, metrics).
