Stuart Muckley and Martin Thomas formed Code Wizards Group back in 2002, bringing together a combined 50 years of coding and video games experience.

Familiarity with database technologies (SQL & NoSQL), such as PostgreSQL, MongoDB, Redis

Experience with matchmaking logic, game session management, and player state persistence
