Technical notes, made publishable.

This blog is the public edge of Personal Knowledge Lab. Private sources, AI drafts, review cards, and unfinished study notes stay inside PKL; only reviewed blog posts are published here.

The main topics are SAP and ABAP learning, cloud architecture, AI agent workflows, and the practical notes that turn daily study into reusable understanding.

Most posts start in Obsidian or PKL's writing studio, then go through explicit review before they become public.
