Amazon SP-API Desktop Automation

I run DAWGLOGZ out of Chicago and need an expert who already speaks Amazon Selling Partner API fluently. Your job is to connect directly to our Seller Central account, read every Buyer-Seller Message, recognise which charity option (A–E) the customer selected, and log that choice alongside the matching order in a small database you set up.

Each month the system must also pull Sales Tax and Order data with the Reports API, crunch the numbers, and output exact donation totals per charity. As soon as a choice is detected, the buyer should automatically receive a Donation Confirmation reply through the Messaging API—nothing else, just that one acknowledgement.

I prefer a lightweight desktop dashboard so I can view real-time charity counts, individual orders, and month-to-date totals without opening a browser. Whether you build it with Electron, Qt, or another framework is up to you as long as it installs cleanly on Windows and shows the data in a clear, filterable interface.

Core deliverables:
• SP-API authentication via LWA/OAuth and role setup
• Message parsing, charity code detection, order-matching logic
• Database schema and persistence layer
• Monthly donation calculation using Reports API pulls
• Automated Donation Confirmation reply workflow
• Desktop dashboard with live metrics and basic export to CSV

Acceptance will be based on:
1. End-to-end test in my live Seller Central account (sandbox first, then production)
2. Accurate logging and donation totals across at least one full day of orders
3. Successful delivery of the Donation Confirmation message within 15 minutes of receipt
4. Smooth desktop installer and clear README

Because our data is sensitive, I can only work with someone physically located in Chicago, Illinois for occasional in-person sessions. If you have verifiable SP-API projects under your belt and can start soon, let’s talk.
