Everything I've made

Packing problems

2026 · optimisation

12 verified improvements to best-known values in Erich Friedman's Packing Center, across ten cells and four tables (two of them records that had stood since 2007)! Each packing is reconstructed from the incumbent's published image, then converged exactly: freeze the contact topology, solve by SQP, repeat. Every claim was reproduced blind by a third-party verifier.

BatchFold

2026 · computational biology

The parallelisation and batching layer for protein folding models, all inside Claude. 28 MCP tools and five skills over a Cloudflare Worker, a SQLite database and an object store, running on your own machine.

Mind

2026 · agent infrastructure

A memory backend for AI agents, modelled on human memory. Agents send raw perceptions into Mind and ask it for the smallest useful memory packet before they act. Mind handles storage, consolidation, recall, corrections, retention and evidence packaging.

Pinky

2026 · agent UX

A menu bar app that watches your screen and walks you through a workflow step by step. Do the process once while Pinky watches and it writes a Markdown skill file you can replay later or hand to another AI tool.

Patience

2026 · agent infrastructure

A TypeScript framework for queue-based AI agents. One task can enqueue others and later tasks can wait on earlier ones, so a run forms a DAG.

OttoProp

2025 · workflow automation

An AI employee that handles a property maintenance request from first message to resolution, sending the emails and updating the CRM along the way. One of 11 teams invited to the Ada Ventures hackathon for £100k in funding.

Latch Writing

2026 · macOS

A stripped-back note-taking app with a focus lock mode stops you switching apps mid-draft.

Malaria detection

2020 · computational biology

A Faster R-CNN ResNet model built in TensorFlow that spots malaria parasites at 90% test accuracy, with a Streamlit frontend on top.

And the ones I was paid for

Briefcase

Jul – Aug 2026

Founding engineer. An AI autopilot for accountants and bookkeepers. I worked on mileage claims, the autopublish rate, the AI memories system, and self-healing software that investigates and repairs infrastructure failures in production.

Novartis

Aug – Sep 2025

ML research intern, invited back. Research on Bayesian modelling for dose-finding studies. I built an LLM tool inside an RStudio sandbox that writes models and corrects its own errors (roughly Cursor for Bayesian inference) and gave the group a seminar on Bayesian modelling with AI. Early form of recursive self-improvement.

The Bot Factory

Apr – Sep 2025

Cofounder. An AI automation agency for UK businesses. Our clients included property managers, commercial finance brokers, online communities. Learned the difficulty of building systems for the real world.

Novartis

Sep – Oct 2023

ML research intern. Built an LLM system that pulls structured data out of clinical trial reports, and gave a seminar on using LLMs in clinical informatics. Early research on multi-step workflows.
