Most of this book was born in Manchester Central Library’s reading room, but it was the team at Apress—Nancy Chen, Louise Corrigan, and James Markham—who’ve transformed it from a long-running side project into something that shipped. I’d also like to thank Brandon Scott for acting as technical reviewer, for his suggestions, and for sense-checking me!

The skills and knowledge I’ve gained that have qualified me to write this book have come, to differing extents, from everyone I’ve ever worked with professionally. Every article I’ve read, tweeter I’ve followed, and conference speaker I’ve watched, combined with those whom I’ve paired with, mentored, or had my code reviewed by has contributed to the sum of knowledge that’s gone into this book. I want to specifically call out the BBC Knowledge & Learning team, where I grew from a graduate to a senior developer, and the TRIP project team at ThoughtWorks, who gave me the space to grow my technical ability.

There are a number of people I wish to call out who’ve shaped my worldview into what it is today, which I express through my work. My Auntie Jayne, who as godmother steered my ethical development; Rosie Campbell, who introduced me to intersectionalism; Rebecca Forbes, who kept me sane at the chaotic start of this whole project; Alina Apine, who continues to encourage my radicalism; and, most importantly, my Mum and Dad, without whom I would be nowhere.
