I’m a Senior Game Development Specialist with over eight years of hands-on experience building and leading gameplay systems in Unreal Engine and Unity. I’ve worked across AAA and mobile projects including Remnant II, The Quarry, and House of Ashes where I’ve designed everything from AI and combat systems to cinematic tools and co-op networking. I’m big on performance, scalability, and keeping teams moving fast. I love digging into Unreal’s guts, optimizing code, and building tools that make life easier for designers and artists. I’ve led small engineering teams, mentored juniors, and worked closely with art and production to ship solid, high-performing games across PC, console, and mobile.…I’m a Senior Game Development Specialist with over eight years of hands-on experience building and leading gameplay systems in Unreal Engine and Unity.
