Data, models & applied AI, distilled into useful references.
I'm Omar — a data scientist and ML engineer with 26+ years across credit, telecom and EDA. This site is where I keep my cheatsheets and field notes on machine learning, LLMs, agents and the tools I actually use.
Two libraries, one mission
Quick references for fast lookup, long-form articles for deeper understanding.
Cheatsheets
Concise reference guides for the tools and libraries that show up in real data-science and ML work. Skim them, bookmark them, print them.
Browse cheatsheets →Blog & Articles
In-depth articles, capability tours and field notes on emerging AI models and tooling — things I learned from actually running them, not just reading about them.
