Authors of Head First Kotlin
Dawn Griffiths has over 20 years experience working in the IT industry, working as a senior developer
and senior software architect. She has written various books in the Head First series, including Head First
Android Development. She also developed the animated video course The Agile Sketchpad with her
husband, David, as a way of teaching key concepts and techniques in a way that keeps your brain active
and engaged.
When Dawn’s not writing books or creating videos, you’ll find her honing her Tai Chi skills, reading,
running, making bobbin lace, or cooking. She particularly enjoys spending time with her wonderful
husband, David.
David Griffiths has worked as an Agile coach, a developer and a garage attendant, but not in that order.
He began programming at age 12 when he saw a documentary on the work of Seymour Papert, and when
he was 15, he wrote an implementation of Papert’s computer language LOGO. Before writing Head First
Kotlin, David wrote various other Head First books, including Head First Android Development, and
created The Agile Sketchpad video course with Dawn.
When David’s not writing, coding, or coaching, he spends much of his spare time traveling with his
lovely wife—and coauthor—Dawn.
