Thou shall design for retries before designing for speed. Payments fail more often than they succeed on the first try.

Thou shall remember that every bug is someone's money. In fintech, a "small bug" can mean a customer loses trust. That's much harder to fix than code.

The 10 Commandments of a Fintech Backend Engineer in Nigeria 👇

Never trust a successful API response.
Always verify a webhook, reconciliation, or the ledger.

Not the payment provider. Not Redis. Not your frontend.👇

Thou shall log enough to investigate fraud, but never enough to leak customer data.

Thou shall not deploy on Friday unless you're ready to spend your weekend working.
