Apps and services you ship live here — name, one line, and a link.

Web developer, 25+ years — PHP & React, now deep in what AI changes about building software.
I build for the web in PHP and React and have done for 25+ years. Right now I'm fascinated by what AI is doing to the craft — AI-assisted development, agentic tooling, and automating the tedious parts of building software. This is my home base: what I build, what I write, and where to reach me.
Building
Apps, services, and tools I've shipped or am working on.
Writing
Notes on engineering — i18n, AI-assisted development, and the tools I actually use.
Elsewhere
Longer conversations and video live off-site.
The personal side
Away from the code, I write about recovery, neurodivergence, and rebuilding a life on my own terms — some of it in Russian. It's quieter and slower than the engineering work, and it lives further down the page on purpose. If that's why you're here, the blog is the place to start.
