PHP Script custom API Integration

Hello,

I am looking for a skilled PHP/Laravel developer to perform a **custom integration** for my Xaxino v3.5 casino script. The goal is to add support for my own **external Games Provider API** and manage these games through a dedicated **admin panel**.

## Resources
- Xaxino v3.5 script: https://pixeldrain.com/u/YjD2i4DY
- Games API documentation: https://docs.google.com/document/d/1mXWSCHBkizCwpIDnR-YZs0D1mQUPYdX6irXHdc6nWKg/edit?tab=t.0

## Requirements
1) **Provider integration**
- Integrate my API as a games provider within Xaxino (Laravel).
- Store provider settings in admin (keys, URLs, callback endpoints, environment support).

2) **Admin panel**
- Add a section to manage external games: add/edit/disable/sync.
- Handle metadata: categories, ordering, thumbnails, and featured flags.
- Support re-sync/update of game lists without duplication.

3) **Gameplay flow**
- Users can launch provider games via UI (iframe or redirect, matching API spec).
- Handle session creation securely per API spec.

4) **Wallet / transactions**
- Bets, wins, and rollbacks are reflected in user balances.
- Ensure idempotency, ledger integrity, and audit logs.

5) **Logging and security**
- Admin-visible request/response logs with masked secrets.
- Callback verification (signature/HMAC/token, IP restrictions if needed).

## Deliverables
- Fully functional Xaxino integration.
- Migrations, admin UI, and setup/configuration documentation.
- Clean Laravel code, ready for production.

I require a freelancer who can handle both backend API integration and admin panel development, ensuring smooth, secure, and maintainable implementation.

Please provide:
- Estimated timeline and cost.
- Previous relevant experience.

Thank you,
Mina
