Experienced Laravel Developer for Mascot Gaming Api Integration

We are seeking an experienced Laravel/PHP backend developer to integrate the Mascot Gaming API into our existing sweepstakes-style gaming platform. This is a contract project with a clear milestone-based approach.

Key Requirements:

Strong experience with rest api integrations is essential.
Proven work with gaming or casino APIs (such as Mascot, Jili, CQ9, Spribe, etc.) Is highly preferred.
Ability to sync real-time wallet balances, handle bets, process wins, and manage comprehensive transaction logs.
Expertise in setting up secure connections using API keys, tokens, and signature verification.
Proficiency with MySQL for robust database management and accurate tracking of player balances.
All code delivered must be clean, thoroughly tested, and designed for scalability.

Milestone Approach:

Phase 1 (Test Milestone): Establish connection to the Mascot Gaming sandbox API. This phase requires running a simple "ping" or wallet balance request and successfully returning data to confirm a working connection.
Phase 2: Implement full game launch endpoint integration, including the development of secure bet and win transaction processing.
Phase 3: Conduct final comprehensive testing and ensure seamless delivery and integration into our existing Laravel platform.
