Everything I build, in one place, whatever name it ships under. Four things worth your time, then the rest. Each one with the screenshots, the videos, and the one-pagers behind it.
The smaller work.
Pipelines, tools, and experiments that earn their keep but do not need a chapter. Some of the best work is under NDA.
About.
I am Alexander. I have built software for a long time, led engineering across four acquired startups, and was founder and CTO of one. Now I build with AI agents every day and talk about it as I go. This page is where the work lives; the newsletter and the videos are where I think out loud about it.

New work shows up here first. The story behind it goes out in the newsletter.
