About

I’m a professional geek and data wizard. I’ve been using computers since I could sit in a chair and press buttons (thanks for the family BBC Micro).

After working in education and then systems administration, I got into data warehousing and BI in 2009 and found a love for working with data.

This blog is a collection of older notes on database and data warehousing tips, tricks and solutions which I’m sharing. But also a place where I can write about things I’m learning.
