You will get Backend Reliability Audit — 3 Concrete Failure Modes + The Fix For Each
Project details
I audit Python and Go backends and return three concrete failure modes — and the smallest change that closes each one. No 40-page deck. No "consider adopting microservices."
If your retries can create duplicates, your gateway loses requests on backend deploys, your callback handler drifts under race conditions, or your scraper gets 429-throttled into the floor — those are the kinds of findings this audit produces. I work the same way I do on my own production systems: anchored to repo evidence, ranked by blast radius, fixable in days not quarters.
