I’m a staff engineer at MongoDB in New York City, specializing in C++ and distributed systems. I wrote Motor, the async MongoDB Python driver, and I’ve contributed to the MongoDB C Driver, 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.
