I Built 4 FastAPI Projects in 2 Weeks — Here's What I Wish I Knew Before Starting

Short summary

The author built 4 FastAPI backends in 2 weeks and distilled practical patterns: reuse Docker and database-migration templates to eliminate repetitive boilerplate setup, configure Celery with prefetch_multiplier=1 and task_acks_late=True to prevent broker timeouts and data loss, and recognize most CI failures are infrastructure issues rather than code bugs. He published a GitHub template combining Docker Compose, Postgres, Redis, Celery, JWT auth, and a working CI pipeline to cut project bootstrap time from hours to minutes.

• •Docker and migration templates eliminate hours of repetitive boilerplate per project
• •Two Celery config lines (prefetch_multiplier=1, task_acks_late=True) prevent most production failures
• •Most CI failures are infrastructure issues (missing deps, config mismatches), not code bugs
