Hi, I'm Dan. I graduated from Harvard with a degree in computer science and economics, and now I run a payments company in San Francisco.
I've loved technology, writing, and teaching for about as long as I can remember. This blog represents my favorite blend of those three topics. I hope you find it valuable, and that you share feedback on my writing/teaching so I can continue to hone my craft! Thanks Kev.
