Projects
Selected technical work
Ramsey Numbers Research
COMP3821 (Extended Algorithm Design and Analysis) research project. Investigated computational bounds on Ramsey numbers and properties of extremal Ramsey graphs. My contributions: computationally disproving the Extension Conjecture and Degree Difference Conjecture via counterexample search on McKay's graph database, and implementing a 3-colour Ramsey graph generator to find lower bounds.
JS Chess Engine
A fully playable chess engine with an AI opponent built from scratch in JavaScript, including move generation, board evaluation, and minimax with alpha-beta pruning.

Wordle Solver
An optimal Wordle solver using information theory — each guess is chosen to maximise expected information gain, consistently solving the puzzle in under 4 guesses.
Try itCoding Challenges
A collection of self-contained interactive projects — minimax Tic Tac Toe AI, Reynolds' Boids flocking simulation, and a Turing Machine simulator with a plain-text rule format, breakpoints, and an automated test suite.
ExploreAI Learns to Play Snake
A neural network trained with a genetic algorithm to play Snake. Agents evolve across generations, with natural selection favouring higher-scoring individuals.
AI Learns to Drive
Cars guided by neural networks learn to navigate a race track through evolutionary training. Raycasting sensors feed into the network; fitter agents reproduce each generation.
8-bit Minecraft Computer
A fully functional 8-bit computer built from redstone logic gates in Minecraft, capable of running custom assembly programs — including Fibonacci and multiplication algorithms.
