Projects

I build to learn. Each one is an experiment with a question behind it.

Agentic AIHardwareVoice

Jarvis Home

A voice assistant for our home, running on a Raspberry Pi. A Claude-powered router sends each request to small single-purpose agents for shopping lists, to-dos, home maintenance, flight alerts and fare drops.

The question: what does it take to make a multi-agent system feel fast, useful and personal day to day, without compromising on privacy?

Game designPhysical productAdtech

AdTech Holdings

A board game of programmatic capitalism. Players build adtech empires, buy deeds across the value chain and try not to get disintermediated.

The question: can a game make the adtech value chain easy to understand, and what does it really take to design and manufacture a physical product?

GamingCreator tools

Roblox games

A small series of games, built on the platform I build ads for.

The question: what does building on Roblox teach me about the creators whose experiences our ads live inside?
