Ship-It Backend Doctor Bundle

Diagnose why Stripe Checkout, the Billing Portal, or your webhooks aren't working: missing signature verification, raw-body mistakes, no idempotency, test/live key mix-ups, broken success and cancel URLs, and subscription lifecycle gaps. Works across Next.js, Express, FastAPI, and serverless, with severity, evidence, and copy-paste fixes for each finding.

Audit local Supabase SQL, migrations, policies, storage rules, and client code for RLS gaps, broad policies, service-role leakage, overbroad grants, and tenant-isolation mistakes. Get severity-ranked evidence, proposed fixes, and verification steps without connecting to or changing the live project.

Diagnose why your Docker Compose stack won't come up: port conflicts, bad or missing env vars, absent healthchecks, volume and permission issues, depends_on that doesn't wait for readiness, networking gaps, platform mismatches, and databases that aren't ready. Reads your docker-compose.yml and logs and ranks the blockers with fixes.

Figure out why your Vercel build or deploy failed without scrolling the whole log. Reads the build log plus your package manifest and framework config to pinpoint missing modules, Node and package-manager mismatches, missing env vars, monorepo root mistakes, and serverless/edge runtime errors, with the likely cause and a fix for each.

Diagnose CI step failures and jobs that fail before steps run. Trace empty-step states and matrix cancellations to evidence, then propose the smallest reviewable fix.
