As an expert in Python with a specialized understanding in Django and related technologies, I am confident in my ability to reverse engineer game packets and decrypt the protocols needed for your Marvel Rivals project. With a solid 6+ years of experience under my belt, I have amassed a range of skills necessary for this task such as my proficiency in PostgreSQL, MySQL, MongoDB, and REST APIs- which are all crucial tools for emulating game server authentication processes.
Moreover, I am also deeply familiar with analytical libraries like NumPy, SciPy, and Pandas – a necessary skillset for accurately extracting and representing player statistics and match history from raw gaming data. And don't worry—I've got you covered on the "lookup-a-player-by-username", "fetch-match-details-by-ID" fronts too.
Finally, let's not forget about my experience in setting up cloud services with AWS including proxy servers, WebSockets, and concurrent programming—a skill that will be undoubtedly valuable for your project moving forward. With these combined abilities and my proclivity for team collaboration(I love that you highlighted this), I'm not just your perfect fit; I'm your partner in making this stats website a success.
