Leah Buley is the author of The User Experience Team of One and an analyst at Forrester Research, where she researches and writes about design, research, and the user experience field after 15 years living in it. Prior to Forrester she worked as a design strategist at Intuit, where she worked on the future of business and personal finance, and as an experience design lead at Adaptive Path, a pioneering user experience design consultancy. She started her career in the late 1990s as an opinionated Web developer. Through self-taught tinkering she gradually made the transition to user interface design, and then from user interface design to the broader discipline of user experience. She spent the early 2000s as a UX team of one in a range of financial and information service companies. That experience led her to write The User Experience Team of One, a book she wished she'd had in the early days of her career.

She writes and speaks regularly on this topic at conferences such as SXSW, UX Week, UX London, Agile, the IA Summit, and Webvisions. Her workshops and presentations have a reputation for being hands-on, high energy, and a little bit quirky.
