Shakhawat’s NotesData, AI & useful systems

Hi, I’m Shakhawat

I turn messy data into
useful systems, then write down what I learn.

I’m a Data Scientist in Germany, working where AI meets public services. This is my notebook: the guides I wish I’d had, the questions I’m still working through, and the occasional thing I got wrong the first time.

A reading path

Kubernetes, from the first container to the whole cluster.

16 guides, written to be read in order. Each one picks up exactly where the last one stopped. About five hours and a half in total, so maybe seven cups of tea.

বাংলাWritten in Bangla, with technical terms kept in English, the way most of us actually talk about them at work. Prefer English? Every guide has an English version, translated with AI.
