Available to hire
I’m David Gautrey, a senior Unity and Unreal developer with over 35 years in the gaming industry. I’ve led teams, shipped games across generations from ZX Spectrum to modern consoles, and I excel at turning creative ideas into solid, playable experiences. I’ve worked across all phases of development, from systems design and AI to art pipelines and tooling, always focusing on immersive player experiences and strong hardware awareness.
I’m passionate about mentoring others and sharing knowledge, which I’ve done as a lecturer at Bolton University and through leadership roles in multiple studios. I enjoy pushing new technology—embracing Unreal 5 features like Nanite and PCG, exploring Unity DOTS for large-scale enemy populations, and refining build and test processes to keep projects on track while delivering top-tier games.
