After handling web production in general at an advertising agency, Eri became independent as a freelancer in 2005. Realizing a preference for coding over design, she transitioned to a front-end engineer. While developing CMSs, EC sites, and various websites, from corporate sites to landing pages, she also pens HTML&CSS and CMS-related books and teaches courses. She joined her husband’s company, Driveshaft Inc., in 2022. Eri loves dogs, travel, photography, games, and cooking, and she is a hula dancer.
