Frequently asked

Why FastAPI over Flask or Django?

FastAPI is async-first, type-driven, auto-generates OpenAPI docs, and is the default for new Python services in 2026 startups. Flask and Django still ship, but new builds usually pick FastAPI.

Does the track cover deployment?

Yes — multi-stage Docker, Render / Fly.io / single-node k8s, plus the production patterns (rate limiting, caching, observability, blue/green vs canary).

Do I need Postgres knowledge?

Some. The track teaches async SQLAlchemy + Alembic against Postgres. You don't need to be a DBA, but knowing what a foreign key is helps.

What's the capstone?

A multi-tenant SaaS skeleton: auth, billing webhooks, background jobs, observability, deploy. Same shape as Stripe / Notion / Linear's actual backends, at 30k feet.

Will this prepare me for FAANG backend interviews?

Partially — pair it with the System Design + Interview Prep tracks. Together that's the full junior backend bundle.
