Perfect — AWS SES is totally fine for this setup. You're right: If your SES account is still in sandbox mode, you'll need to verify every recipient email address before you can send to them. Once you move SES to production mode, you can email any address without pre-verification. ✅ Summary of What I'll Build You want a standalone Flask backend with: ✅ Passwordless email login ✅ Using AWS SES for sending login magic links or codes ✅ Firestore (still okay?) as the database for storing standups + user records ✅ No frontend integration — just pure Flask API routes and you'll handle the UI separately ❓ Final Clarification Before I Generate Code Please confirm two final details so I generate the right structure: 1. Verification Method Which one should I implement? Option API Flow User Experience Your Pick? A) Magic Link POST /auth/request → GET /auth/verify?token=... One-click login from email ✅ Easiest for user B) 6-Digit Code POST /auth/request → email code → POST /auth/verify Enter code manually More control 👉 Pick one: Magic Link or 6-Digit Code 2. Database Choice Are we still using Firestore? Or do you prefer: Option Pros Your Pick? Firestore No server maintenance, easy Already planned Postgres More structured, Railway-native SQLite Easiest local dev 👉 Confirm: Use Firestore or pick another DB Once you answer with something like: Magic Link + Firestore I’ll respond with: ✅ Fully structured Flask project ✅ Including: /auth/request and /auth/verify /standup/save and /standup/today AWS SES email sender module JWT token-based session system All in clean modular code (Blueprints or Routers). Just confirm those 2 details and I’ll deliver the full backend implementation in one go.
