About the Author
Natalie MacLees is a frontend web developer and UI designer, and the founder and
principal of the interactive agency Purple Pen Productions. She founded and runs the jQuery
LA users' group and together with Noel Saw, she heads the Southern California WordPress
user's group, organizing WordPress meetups, help sessions, and workshops. She was the lead
organizer for WordCamp Los Angeles 2013 and 2014 and organized the first annual Website
Weekend LA. She's also the founder of the Los Angeles chapter of Girl Develop It, bringing
affordable and accessible coding classes to the community.
She makes periodic appearances on the WPwatercooler podcast and co-hosts the WP Unicorn
Project podcast with Suzette Franck. She makes her online home at nataliemac.com.
Her obsession with the Web began when she bought her first computer in 1996 and promptly
used it to build her first website. She spends the few moments she manages to be offline each
day watching baseball, crafting, reading, baking, belly dancing, collecting Hello Kitty items,
and avoiding avocados and olives at all costs.
