Jonathan Leahy

Full-stack developer. Builder of things.

Staff Engineer at Pismo, A Visa Company, building payments infrastructure at scale. On nights and weekends I'm running an experiment: can a whole software company run on AI agents? I've tried versions of this before — this one's working well enough that I'm pushing it further, to see what an agent-driven company actually becomes.

Featured Projects
