Joey Faulkner
Research Engineer at PLAYERUNKNOWN Productions
Sheffield, England, United Kingdom
Summary
🤩
RockstarJoey Faulkner is a Research Engineer with nine years of experience building secure, production-ready systems and machine learning infrastructure, currently contributing at PLAYERUNKNOWN Productions in Sheffield. He blends back-end engineering and ML research, having improved NLU pipelines in Rasa and implemented robust security, certificate handling, and user-management features for the Python OPC UA asyncio library. Joey’s work spans full-stack contributions and low-level server security, demonstrating a rare comfort with both conversational AI featurizers and encryption/authentication in industrial protocols. He is pragmatic about maintainability—renaming variables, adding tests, and improving error handling—to keep complex systems reliable in production. Colleagues know him for shipping practical, well-tested changes that bridge research ideas and operational needs. An interesting detail: he’s equally at home tweaking N-gram featurizers for better language understanding and hardening server endpoints for secure device communication.
