One time Technical Assignment.

I am looking for an experienced developer for a limited one-time technical assignment involving an existing production application. The project uses: - Upstash Redis - Redis Lua scripting - Node.js / TypeScript - Vercel The task involves reviewing an existing recovery package for a Founder Admin access issue. Initially, the work is strictly read-only. No production database writes, role changes, deployments or configuration modifications are authorized. Before proceeding, could you please confirm: 1. Have you worked directly with Upstash Redis in production? 2. Do you have practical experience writing and reviewing Redis Lua scripts? 3. Have you implemented atomic compare-and-set operations? 4. Have you handled secure Redis backups and recovery? 5. Can you independently review an existing Node.js/TypeScript maintenance script without making production changes? Please share one relevant example of your previous work and your estimated fixed price for this initial review. Thank you.
