Hi, I'm Vivek! I maintain and contribute to OpenSkill, a collection of models and their prediction methods specifically designed for competitive multiplayer video games, and scenarios where large scale ranking systems are need. Are you a company, video game or developer of software using the methods (or derivatives thereof) of OpenSkill? If so, a small donation of funds will go a long way towards both motivating and helping me focus more of my time on fixing bugs, and extending the ranking systems for more use cases.
