I gave regularly to kiva,org, charitywater.org & local causes. I do the occasional programming volunteer tasks when I have time & find a fit (usually small things like giving web site support to small local charities).

On the side I'm trying to work more with #a11y & accessibility, as well as a lot of mentoring & teaching in programming

Sorry, I'm not a billionaire with too much time on my hands. With two teenagers that's the best I can do right now.
