A marketplace for buying and selling second-hand sailing gear: sails, hulls, masts, fittings.

I started it with almost no web or database experience, so the project became the course. What exists today is the business model, the domain model and the database schema; the application itself does not. Modelling before coding was a decision, not a delay: the schema already separates product families with their own validated attributes, and that is what later decides what can be searched and filtered.

A voice assistant that runs entirely on my Linux machine: I speak to it, it listens, and it answers out loud.

No audio leaves the machine — transcription and speech synthesis are local models, and only the language-model query travels over the network. I built the whole thing with AI assistance, which is also where I learned to review code I hadn't typed line by line.

A model that decides how to split a portfolio across equities and crypto, and when to move into cash instead.

Built by three of us at the UMA FinTech Chair hackathon in March 2026, where we came third. I designed the tactic: when to enter, when to stay out, and having the model's response grow logarithmically rather than linearly. No machine learning — the decision comes from rules you can read and argue with, which over forty-eight hours is an advantage rather than a limitation.
