#Coding isn’t the main differentiator anymore. What really sets you apart is how you design and maintain systems when things go sideways: #idempotency, retries/timeouts, consistency, rate limiting, and #observability.

Retrying a POST after a timeout creates a second write, not a second attempt. A timeout tells you the outcome is unknown, not that the request failed.

A payment endpoint survived every retry because of one unique index nobody documented. Here is how to spot that accidental guarantee before someone drops it.

Every exactly-once mode is at-least-once plus dedup inside one system. The moment your handler calls an external API, the guarantee ends at your function boundary.

A successful retry can repeat the damage.
A timed-out payment may already be complete. Pharos Production builds event-driven wallet systems. Recovery must account for effects already performed.
