Oracle & databases
Administration, troubleshooting, performance and useful things worth remembering.
Personal notebook
Databases, AI, Apple — and time outdoors.
My name is Octavian-Codrut Popescu, an Oracle DBA based in Switzerland. This is where I publish practical notes, experiments and observations about the technologies I work with, the tools I enjoy, and the roads and trails I explore away from the keyboard.

AI / MLAbout
A technical life, with room for trails.
Born in Bucharest in 1974, I have lived in Bülach, Switzerland since 2022. I work professionally as an Oracle DBA. Away from database systems, I’m interested in AI, machine learning, macOS and Apple products — and I spend free time cycling and hiking.
