About

I'm a Year 13 student and part-time Full Stack C# developer in London, rebuilding a law firm's debt recovery platform. Outside of professional software development, I investigate the limits of AI systems and teach computer science through lectures as the founder of my school's Computer Science Society.

    Youth AI Literacy Programme · King's Cross

    Five days building and testing an AI project from scratch. I led research and evaluation for a Socratic teaching agent and coordinated the team's technical work. We placed 2nd of 15. Also tested BBC R&D's Pathfinder platform and talked my feedback through with their team.

    Software engineering work experience

    How insurance requirements become software: Brossa, Artificial's Haskell-inspired language, mapping ISO 27001 controls to NIST, and client demos. I spent two days trying to break the AgLabs human-to-agent and agent-to-agent platform, then presented the orchestration and workflow issues to the team.

Epistemic Topology

Do a language model's internal states look different when it is about to give a wrong answer? A PCA baseline on residual-stream activations didn't separate them linearly, so I moved to persistent homology: Vietoris–Rips complexes over the activations, tracking which loops survive as the radius grows.

Spectral Provenance

A convolutional network that flags AI-generated audio. Short-time Fourier transforms turn each waveform into a Mel-spectrogram, and the model looks for patterns a human voice doesn't make, such as frequencies that stop dead.

Lyra Pulse

People won't say how they really use AI at work if they think HR can trace the answer. Lyra Pulse randomises every response on the device, under a managed privacy budget, and treats the server as already compromised. Individual answers are deniable; the aggregate is still accurate.

The Door Is Not Locked

Free will as a capacity to respond to reasons. A compatibilist case: freedom comes from understanding, reconsidering and acting on reasons, not from escaping causation.

“Clear, focussed, and well-written essay, which demonstrates a strong understanding of the relevant issues.”

The Global Financial Crisis

The 2008 financial crisis, argued through one idea: securitisation separated risk from responsibility, which is how losses in the US housing market became a global funding crisis.

Philosophy of economics

The Sign of the Feedback

What makes economics a discipline when the people it studies read what it writes. Publicity strengthens coordination rules and dissolves exploitable ones, so a complete economic claim has to state how being known will alter the evidence for it.

“An ambitious, genuinely original argument that threads Lucas, Goodhart and MacKenzie into a single thesis, with a command of the literature well beyond school level.”

Philosophy of mind

Could a machine think and feel?

Thinking and feeling may be different problems. Computation might be enough for thought; feeling could need something a machine doesn't have: something to lose.

“If we ever create a machine that can feel, are we also creating something that can suffer?”
