Auth → Sessions
Keeping an established session safe for its whole lifetime: cookie flags, revocation, CSRF defenses, and concurrent-session visibility.
Payments → Stripe
Stripe-specific integration rules on top of payment-system-basics: key handling, Elements, SCA/3DS, and treating webhooks as the source of truth.
Testing & Quality → Other
A pragmatic testing pyramid and CI discipline focused on tests that actually catch real regressions, not coverage-number theater.
Translation & Languages → Translation Style
Rules for producing translations that are faithful and natural at once: register, glossary discipline, false friends, locale formatting, and what to leave untranslated.
Payments → Webhooks
How to receive any provider's webhooks safely: signature verification, idempotent processing, fast acknowledgment, and ordering assumptions.
