Azul is a game engine I built from scratch in C++ across three courses, starting with the memory manager and scene graph and ending with GPU-skinned character animation.

The C++ core owns all of the game state and rules, and separate clients in C#, Python and TypeScript drive it through a single versioned C ABI. The point was to understand how binaries talk to each other across languages.

This was an optimisation contest where everyone started from the same particle system and had to make it faster without changing what it draws. Rewriting it around SIMD and data-oriented design brought the frame from 107.68 ms down to 14.71 ms.

C++ · SIMD (SSE4.1)

Built up from raw sockets into networked multiplayer, adding client-side prediction and dead reckoning to keep the clients consistent with each other.

C# · Lidgren · TCP/UDP

Wrote a GPU image-processing pipeline that ends by counting the coins in a photograph, along with triangle-strip generation on the GPU, timing every variant against a CPU baseline.

CUDA · C++

An OpenGL 3D renderer implemented with GLEW and GLFW backends, supported by Assimp for model loading and Dear ImGui for UI elements. This is a hobby project created to learn the principles of graphics programming.

This is a playable Space Invaders built over seven sprints, with each sprint introducing one or more design patterns into the game loop.

C# · Azul framework

This is a 3D environment created using C++ and OpenGL, as output for the Graphics Programming module at ICAT.
