Antony O'Neill
Building with AI, ML, and data. I ship production web apps.
MSc Computer Science & AI student. Before that, 17 years as a mechanical engineer. I'm used to taking apart complicated systems to figure out what's actually broken. These days I'm doing the same with code and data.

Technologies and tools I work with.
Featured Projects
Things I've built and put in front of real users.
Agent Office
Pixel-art virtual office that visualises your AI agents working in real time. Watch Claude Code agents spawn, sit at desks, take coffee breaks, and chat in a Slack-style panel — isometric, animated, and popular on social media.
Jarvis
Personal AI assistant CLI built around Claude. A bridge architecture lets it talk to your apps, run plugins, and keep conversational state across sessions. Docs are hosted at /arc so you can read it without cloning anything.
Deep Q-Learning Snake Agent
Reinforcement learning agent that learns to play Snake with a deep neural network. I ran a stack of experiments to see how network size, memory buffer, and environment changes actually affected learning.
Twitter Sentiment Classification
Entity-level sentiment classifier across six architectures, from a plain MLP up to fine-tuned transformers. Twelve runs, head-to-head: a tuned MLP topped the leaderboard at 98.6%, beating RoBERTa at a fraction of the training cost.
Heart Disease Classification
Binary classifier predicting heart disease risk. I compared Random Forest, SVM, and Neural Networks across nine configurations. Random Forest came out on top at 85%.
Keep It What
Full-stack e-commerce platform for personalised gifts. Real-time product customiser, Stripe checkout, and an admin dashboard for orders and inventory.
Doom Scroll Detection
Webcam tool that watches your posture and phone usage to catch the doom scroll. Uses MediaPipe for face and hand tracking, YOLOv8 for phone detection.
Open Source
What I've been pushing lately.
Lab
Small experiments, mostly around interaction and motion.
Let's work together
I'm finishing my MSc in AI and looking at data science, ML engineering, and software roles. Happy to talk about graduate schemes, contracts, or anything interesting.
