Most problems that look like technology problems are really why-is-this-still-done-this-way problems. I find those, design the way out, and stay until people actually use it.
I am most useful in the messy early part of a problem, before anyone is sure what the answer is. Outside the work I am usually building something small for myself, running it off a server in my apartment, or outdoors somewhere. Based in Boston, open to what is next.
