வணக்கம், I’m David

Engineer with a designer’s eye.

I build real products with AI agents, and sweat the details they miss.

Selected work(04)

Four products from the last year, each shipped end to end with agents in the loop.

How I build

Most of my recent work was built with AI agents. I write the specs, the context files and the design rules, review every diff, and let agents write a lot of the code. On Wave commits on GitHub (opens in a new tab), 191 of 220 commits carry a Claude co-author line.
