RetroEngine

My own DirectX 12 engine, written from scratch. It simulates the beam, the phosphors, and the glass of a real CRT instead of faking it with a filter. It's grown from a renderer into an engine with an editor, and there's a game being built inside it now.

• Stable 60 FPS on a Radeon 660M integrated GPU, before instancing or culling
• ECS, terrain streaming, shared-ownership texture cache
• ImGui editor with a live GPU memory debug panel

The Quantum Conflict

A space dogfighting game made by a two-person team and published by FlashPoint Games. I handled rendering and effects, plus content and Endless Mode.

• Six custom URP post-process effects in HLSL, unlocked at runtime as in-game "dimensions"
• Raymarched Mandelbulb boss with soft shadows and fractal coloring
• Screen-space lensing for black holes and wormholes, time-bubble fields, and a VHS-style rewind effect

Cozy Holes

A relaxing digging adventure, from the same two-person team. I handled world building, terrain carving, effects, and lighting.

• Staged, event-driven terrain carving on voxel terrain, with biome-aware texturing
• Built most of the island: caverns, tunnels, lava pits, and temples
• Fixed underground rendering (sky, weather, and water), plus the stylized shading and bloom controls

“A brilliant reminder of the simple joy of digging.” VICE, on the demo

Tools that learn

Side projects at the overlap of machine learning and real-time content.

• Local LLMs and retrieval-augmented pipelines since 2023, running fully offline
• Predicting light direction with a CNN trained on synthetic data from Unity
