Callum James Henderson-Begg (born 17 January 1981), known as Cal Henderson, is a British computer programmer and author based in San Francisco.
Education
[edit | edit source]Henderson attended Sharnbrook Upper School and Community College,[1] and Birmingham City University where he graduated with a degree in software engineering in 2002.[2]
Career
[edit | edit source]Henderson is best known as the co-founder and chief technology officer at Slack, as well as co-owning and developing the online creative community B3ta[3] with Denise Wilton and Rob Manuel; being the chief software architect for the photo-sharing application Flickr[4] (originally working for Ludicorp[5][6] and then Yahoo); and writing the book Building Scalable Web Sites[7] for O'Reilly Media.
He has also worked for EMAP as their technical director of special web projects[8] and is responsible for writing City Creator[9] among many other websites, services and desktop applications. Cal was the co-founder and VP of engineering at Tiny Speck,[10] the company whose internal tool transitioned into Slack.
Henderson's connection to Stewart Butterfield and Slack began through a game developed by Butterfield's first company, Ludicorp, called Game Neverending. He ran a fan website dedicated to the game and broke into an internal Ludicorp mailing list. Instead of repercussions, Butterfield hired Henderson to work for his company.[5]
Personal life
[edit | edit source]Henderson is color blind, and has worked on applications to make the web more accessible to the color blind.[4] He is also a frequent contributor to open-source software projects and runs a number of utility websites, such as Unicodey, to make certain programming tasks easier.
Politics
[edit | edit source]In August 2022, Henderson contributed $50,000 to The Next 50, a liberal political action committee (PAC).[11]
