Working on DOOM: The Dark Ages

Silverstone, England, United Kingdom

Collaborated with designers, backend, and competition teams weaving different elements of the MMO racing ecosystem into the Unreal Engine game, ensuring persistence on different platforms.Key Accomplishments:- Developed a lobby for friends from start to finish using Nakama Plugin for Unreal Engine, addressing the critical need for social systems in the game's genre, and providing an essential feature that enhances the overall multiplayer experience.- Migrated user registration and authentication logic from GameSparks to Nakama and reworked its UI to a new design. That migration was an important step in the transition process between platforms, which ultimately greatly benefited the company.- Implemented a Weather editor with a dynamic UI. It enabled creators to simulate realistic weather and provide a customizable experience.- Integrated external content manager service for asset management of DLC elements in the game. This allowed players to access additional assets not included by default but downloaded separately.- Did a major refactoring of Lua's nested game modes. This gave designers a clean, straightforward architecture for nested game modes without workarounds.- Developed an automated pipeline that builds AWS EC2 instances of dedicated servers for game racing sessions. That automation made daily testing much easier for my team.
