I design products, then ship them myself.

Co-founder and only engineer at Arqo. Design engineer at EF World Journeys, where I take checkout and search from research to production front-end, with no handoff. Before that, personalization at Zulily, and employee at The Social Booth in India.

How I build

Arqo has one engineer and a fleet of coding agents. Every agent change clears the same gate, and nothing merges on an agent's word.
