Building useful systems from messy data.

I’m Dauren Moldabayev, a BI and data analytics practitioner based in Kazakhstan. I write about analytics systems, practical engineering, AI tools, and the small products I build along the way.

My work sits between business questions and technical systems: turning raw operational data into reporting, automation, and decisions people can actually use.

This site is where I document the process. Some notes are practical and narrow. Others are about the bigger shift from building dashboards to building data products and AI-assisted workflows.

I’m also developing small B2B products under Lief. Prototypes, mistakes, and useful patterns will show up here as they become ready to share.
