01
Python & FastAPI core
Language fundamentals and framework mechanics every backend loop expects.
- Python typing, decorators, and async foundations
- FastAPI routing, dependencies, and OpenAPI
- Pydantic models for request/response contracts
Python · FastAPI backend interview prep
PythonwithFastAPI
Structured backend engineering — Python fundamentals, FastAPI APIs, databases, auth, and deployment.
Backend loops test API design, data modeling, and trade-offs — not syntax trivia alone.
Build production patterns, defend your architecture in the room — free from basics to system design.
Module 2 of Python track · Pair with Core Python for full coverage
What you'll master
Language fundamentals, production APIs, and interview defense — one structured Python track.
02
Production API engineering
Data, auth, and async patterns you ship before system design rounds.
- SQLAlchemy ORM, migrations, and query tuning
- JWT auth, OAuth2 flows, and role checks
- Background tasks, workers, and reliability
03
Interview-ready defense
Testing, deployment, and architecture trade-offs under panel pressure.
- TestClient patterns and dependency overrides
- Docker, health checks, and observability
- API system design and scenario drills
