Software Engineer
Four years in C++ and C#. Engine systems, AI navigation and a shipped Steam title — the object beside this is a real sparse voxel octree, built in your browser.
Sparse voxel octree
I’ve always enjoyed taking things apart — not just to understand how they work, but why they were built that way and how they could be improved.
Sparse voxel octree
A weirdcore movement shooter set in the liminal space between death and whatever follows. Wall-runs, slides, grapples and slams chain together, and damage scales with how fast you’re moving.

UNITY PLUGIN · C# · SOLO
OctNav: a Unity plugin that carves navigable space out of arbitrary geometry at runtime, then runs A* through it for ground and airborne agents alike. The object at the top of this page is the same idea.
UNREAL · C++ · 2 WEEKS · SOLO
Particle physics with interwoven constraint solving, collision response, and wind with yaw, pitch, strength and variance controls. Constraints can be destroyed at runtime — you can tear it.
PYTHON / C++ · 6 MONTHS · SOLO
Can a hybrid of machine learning and Bayesian inference out-rank Elo? 2,500 real matches, 125 players, all 25 Valorant ranks — and a merged MARS + TrueSkill-inspired model that most players said felt right.
Also — multiplayer networking (UDP/TCP, Steam, LAN) · OpenGL, Vulkan, PS4/PS5 pipelines · Android and Lua shipped to Google Play
Theme: Entanglement, with a countdown. Lab mice tethered to cables tie themselves into knots and die unless you drag them apart. Godot, C#/.NET, seven people, forty-eight hours — first out of 120+ entries. I wrote gameplay code and the music.
The systems work above takes months. This is what the same head does in a weekend.
I’m a systems-oriented engineer in Auckland — four years across gameplay, systems and engine-adjacent code, strongest in C++ and C#. The part I care about is why a structure is shaped the way it is, what it costs, and where it could be better.
B.S.E from Media Design School (2023–2025). Mentored there in 2025 and at NZGDC 2024, and I keep turning up to Global Game Jam. Away from a compiler I’m learning Mandarin.
