I will production grade amazon sp API integration with postgres backend

Generic SP-API gigs sell you a script that breaks the first time Amazon throttles you. I build integrations that survive production traffic.

What you get:

Custom SP-API integration for Orders, Inventory, Pricing, Reports, Listings, Finances, or Feeds APIs (pick what you need) PostgreSQL schema designed for your query patterns not a generic ORM dump Proper auth flow (LWA tokens with auto-refresh, IAM role configuration) Rate limit handling with exponential backoff and queue management Error retry logic that doesn't silently fail Logging that lets you debug 3 months later Docker-ready, environment-variable based config Documented code (TypeScript or Python your pick)

What sets me apart:

I'm not learning SP-API on your project. I run it in production daily across 5 marketplaces. I know which endpoints are flaky (Finances v0 vs v2024), which reports take 6 hours vs 6 seconds, which rate limits Amazon doesn't document properly. I'll save you 40-80 hours of trial and error.

Pre-requisites: You need an active Amazon Seller account with developer access (or be willing to apply I'll guide you).
