I’m a staff engineer at MongoDB in New York City. I wrote Motor, the async MongoDB Python driver, and I’m the lead developer of the MongoDB C Driver. I contribute to PyMongo, asyncio, Python and Tornado. I study at the International Center for Photography and practice at the Village Zendo. You can read more about me or find me on Twitter.
