My name is Derek Graham and this is my personal blog.
I'm a Principal Software Developer working for a very popular business software company in the North East of England. I can't be sure that the opinions I have expressed here are my own so they **definitely** don't represent the views of my employer.
I am an Extreme Programmer, an Infrequent Sketchnoter, a Collector of Programming Languages, a Speaker, a Mob Programmer, a Test-Driven Developer and Struggling Agilista. I am also a STEM ambassador, microbit hacker and project lead for the "Makers & Creators" events at Campus North with Tech for Life UK.
My main areas of interest are in using agile methods to help improve what we ship, test-driven development, unit testing, continuous and deliberate learning, visual thinking, design and, of course, code.
I've had a few requests from people wanting to use sketchnotes or graphics from my site for non-commercial uses. I try to make sure all posts that contain any "art" work are marked with a creative commons licence:
This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
If you follow the link to creative commons, there is a section that describes what you can and cannot use the material for. In short:
Not part of the licence but I'd also really like it if you would let me know, by email or tweet, what you did with it or how it helped you.
You will notice some of the "hero" images on some posts are not drawn by me. They are from [Old Book Illustrations](http://www.oldbookillustrations.com/), a searchable site of public domain illustrations.
