I’m a Senior Staff Research Engineer in MongoDB’s Distributed Systems Research Group. I wrote Motor, the async MongoDB Python driver, and I’ve contributed to MongoDB, the MongoDB C Driver, PyMongo, asyncio, Python, and Tornado. I studied at the International Center for Photography and I work on long-term documentary photo projects. I’m a senior Zen student at the Village Zendo and New Paltz Zen Center.
