This is a blog by Dmitry Dulepov: TYPO3/web developer, AI enthusiast, traveler, and dreamer.

# Notes from my desk

Hi — I'm Dmitry, a TYPO3 developer. This is where I keep notes on the CMS and the AI tools quietly reshaping how I build, with the occasional detour into travel, music, and whatever I happen to be reading. No newsletter and no tracking — just the things I wanted to write down somewhere public.

P.S. Language switcher is at the bottom if you ever need it.
