With my rich history as a Full Stack developer, I assure you that by hiring me, you're signing up for expertise and dedication. While passionately pursuing my craft at "Onseo," I was directly involved in successfully creating over 30 software projects. My back-end skills using Node.js, Python/Django, PHP/Laravel, Java/Spring Boot, ASP.NET, and database skills with MySQL, PostgreSQL, MongoDB, Firebase are all incredibly well-rounded – perfect for applying to your project.
In addition to being adept in system creation which your project will undoubtedly require, I also have extensive experience handling API integration – another key requirement of yours. Given the heavy traffic betting games ordinarily attract, my proficiency ensures I can build a robust backend capable of managing large user volumes without sacrificing performance or reliability.
Although I haven't worked specifically on gaming systems like yours before, my mastery of PHP makes me adaptable and prepared for this new challenge. I firmly believe that my adaptability combined with your vision will yield exceptional results in transforming an idea into reality. Undoubtedly together we can create something extraordinary!
