Senior Programmer

Hutch Games
April 2016 - Present | London, UK

Worked on a number of racing themed titles including: Hotwheels: Race Off, MMX Hill Dash and Top Drives using Unity 3D. Involved in gameplay, UI and audio programming as well as bug fixes and optimizations. Prototyped several new driving concepts making use of the UNet real-time multiplayer service. Developed the physics simulation behind Top Drives as well as a massively parallel physics pre-calculator for server validation. Improved UI performance across all three titles using a combination of optimized UI shaders, hierarchy changes and code solutions. Helped to develop a “best practices” guide for UI artists and currently working on a script framework designed to streamline the process of building and optimizing UI. Developed a cross-project content delivery system; animation tool, and lightweight audio system for realistic engine sounds.

Senior Programmer

April 2015 - April 2016 | London, UK

Senior developer for Ghostbusters Puzzle Fighter on iOS using Unity 3D. Heavily reworked the UI and animation systems to improve performance and stability. Stabilized the frame rate in the match engine by splitting the AI calculations over multiple frames. Used asset bundles to manage the app download size. Implemented high quality / low cost shader techniques for blurring and desaturating UI layers.
