Callum Anthony Stables

Technical Designer with a Computer Science background and 2+ years of professional experience at Moon Studios, working in production environments on complex game systems and tooling. I specialize in bridging design and engineering — building robust tools, workflows, and gameplay systems that scale across teams and large codebases. My experience spans engine-level work, custom editor tooling, and system-driven gameplay development.

Outside of professional work, I have a background spanning level design, game modding and low-level analysis, giving me a deep understanding of existing systems, debugging complex behavior, and extending large, undocumented codebases. I’m interested in roles that value technical ownership, systems thinking, and cross-disciplinary collaboration — in games or broader software engineering contexts.
