Professional work

Unannounced title

I lead development on an unannounced 2D game at Hugecalf. I built the first prototype and the core systems it stands on: physics-driven building, pathfinding that adapts as the world changes, and multithreaded simulation of the game's actors and hazards, from gas and fluids to collapsing terrain.

Much of my work is in rendering and performance. I built the game's 2D lighting on Unity's Render Graph, including radiance-cascade global illumination and soft shadows, write its custom shaders, and keep frame times down on both CPU and GPU. I also build the tools the team uses to test simulations, author lighting and profile the GPU.

Turbo Golf Racing

On Turbo Golf Racing I worked on the platform, online and performance side of the game. I built its Xbox integration, from sign-in to lobbies, matchmaking, and cross-platform parties and invites, fixed the issues blocking certification, and kept the live game stable with crash fixes on both client and server.

I wrote backend logic on PlayFab and Azure Functions for ranked play, matchmaking, leaderboards and rewards, and built the server-side bots. I also owned performance on every platform, holding 120 fps on Xbox Series X and PS5 and 60 fps on Xbox One, and managed asset loading to fit the game within Xbox One's memory. Alongside that I worked on the rollback netcode, the first-time user experience, analytics and the build pipeline.

Avakin Life

At Lockwood I worked on Avakin Life, a social game on mobile and PC, building features alongside the design, UI and UX teams. I focused on two areas: the realtime chat, where I wrote low-latency C# to handle large volumes of messages, and the in-game shop, where I added filters and other UI features.

MiSpace

MiSpace is a wellbeing game for schools, made for Welsh Wellbeing. I built the client on my own, with character customisation, mini games and data reporting, and wrote the Cloud Functions for Firebase that connect it to its Cloud Firestore database.

Bloody Zombies

I worked as a support engineer on the asynchronous save and load for the console versions, and on Xbox controller support for local and online multiplayer.

Pablo's Art World Adventure

I worked on various gameplay features for the mini games and systems in this TypeScript-based web game.

VR gesture recognition

A gesture recognition system built on hidden Markov models that learns hand gestures from controller motion, implemented into two VR games.

This master's led to a published paper:
A Gesture Recognition Model for Virtual Reality Motion Controllers, Computer Graphics and Visual Computing (CGVC) 2020.

Teaching

Wrote and gave lectures on procedural generation, data-driven design in games and mobile programming, and helped deliver Graphics Programming and Advanced Game Programming.
