Kevin Tatroe has been a Macintosh and Unix programmer for twenty years, and an iOS programmer since the hour the iOS SDK released to the public. Being lazy, he's attracted to languages and frameworks that do much of the work for you, such as PHP, Python, and Swift. Kevin, his wife Jenn, his son Hadden, and two cats live on the edge of the rural plains of Colorado, just far away enough from the mountains to avoid the worst snowfall, and just close enough to avoid tornadoes. The house is filled with LEGO creations, action figures, and other toys. Peter MacIntyre has over 28 years of experience in the information technology industry, primarily in the area of PHP and Web Technologies. He has contributed writing material for many IT industry publications: Author of PHP: The Good Parts (O'Reilly); co-author: Pro PHP Programming (APress), Programming PHP (3rd Edition - O'Reilly), Using Visual Objects, Using PowerBuilder 5, ASP.NET Bible, Web Warrior Survey on Web Development Languages, and Zend Studio for Eclipse Developer's Guide. Peter is a co-founder and past co-chair and past board member for the Northeast PHP Developer's Conference held in Boston, MA and Charlottetown, PE Canada for the last 6 years (northeastphp.

org). As well, Peter has spoken several times at North American and International computer conferences including PHPCE 2017 in Warsaw, Poland; PHP[World] 2016 in Washington, DC; ZendCon 2016 in Las Vegas, NortheastPHP 2017 & 2016 (Charlottetown, PE, Canada), Prairie Dev Con 2016 in Winnipeg, MB, Canada, CA-World in New Orleans, USA; CA-TechniCon in Cologne, Germany; and CA-Expo in Melbourne, Australia.
