Project description:
"We operate an eBay purchasing agency website for Japanese customers.
The system was built several years ago in Laravel + Laravel Nova, and now requires a major update to modern eBay REST APIs, removal of obsolete code, and improvements to stability and security.

We already have a very detailed technical specification (both English and Japanese).
You will not need to guess requirements — everything is clearly documented.

Project Scope (Summary)

You will help update and refactor our existing system:

Replace old eBay APIs with official REST APIs
(Browse / Buy / Order / Negotiate)

Keep Proxy Bid using Trading API (PlaceOffer)

Fix Browse API filtering (currently not working)

Implement Buy API checkout session properly

Update Best Offer using Negotiate API
(remove old Trading API BestOffer functions)

Auto-update “Won” status using Order API

Fix admin panel status issues

Fix variation display issues

Add delete button for forwarding service

Fully remove old sniping logic (UI + backend + DB)

Fix financial calculation issues (critical)

Restore monthly sales report dropdown

Fix mailbox overflow issue (SMTP / SPF / DKIM)

Add English/Japanese translation toggle

General bug fixing and security improvements

The system is not built from scratch — it needs repair, cleanup, and modern API integration.

Laravel / Laravel Nova

Strong API experience (REST + OAuth)

Experience with Buy API / Browse API (preferred)

Trading API PlaceOffer experience (proxy bid)

MySQL

Debugging and refactoring existing code

Budget

USD $1500
(Developers may submit higher offers if required for the full scope.)

Clear documentation is provided.

Timeline

4–8 weeks (flexible).
