Systems that hold up under pressure.
From RADAR software on the Eurofighter Typhoon to mission scripting on AAA open-world titles — I design, build and test the systems people rely on to work every time.

01 About
I'm a technically-focused software engineer with a foundation that runs through both ends of the industry: safety-critical defence systems and AAA game production. At Leonardo I work on RADAR software for the Eurofighter Typhoon, and at Build A Rocket Boy I spent three years scripting missions and multiplayer systems for two large-scale Unreal Engine titles.
What ties it together is a habit of building things that get tested properly — automated pipelines, CI integration, and a Test-Driven mindset — whether the output is a mission players will replay or a system that has to be right the first time.

Featured work
Mindseye
Unreal Engine 5LuaMission Scripting
Mindseye
An episodic action-adventure blending cinematic storytelling with explosive gameplay. As Technical Designer I worked across multiple missions from prototyping through polish — scripting mission logic, tuning AI behaviours, and debugging alongside designers, artists and programmers to hit our quality bar. "A Vital Extraction," a high-speed chase through a scripted urban pursuit, was the standout mission I owned end to end.
Available on PC, PS5 & Xbox
Everywhere
Unreal EngineOnboardingSandbox Systems
Everywhere
An AAA open-world title, currently in Alpha. My focus was the game's introductory missions — the onboarding sequence that teaches new players core mechanics and systems. Getting that first hour right meant carefully pacing controls, objectives and sandbox elements to set the tone for everything that follows.
