Speaking

I love telling a story, whether about code or about life. I've spoken at conferences all over the world, from Barcelona to Paris to Boston and (usually virtually) to meetups from Guadalajara to Stockholm to Sydney.

My public talks are 'free as in beer'.  I deeply appreciate those who do the organizational work that make us a community; if you're a non-profit putting together a public event, I'll happily speak for free.

I fear my schedule fills quickly.  If you plan to get in touch, sooner is always better than later.

I saw your talk at RailsConf today, and I was very impressed. You are the most gifted, engaging speaker I have heard so far at this year’s conference. Thank you for sharing your knowledge and experiences! -
