I’m a senior staff engineer at MongoDB doing research at MongoDB Labs. I live and climb in New Paltz, NY. 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 practice at the Village Zendo and New Paltz Zen Center. You can read more about me or find me on Twitter or Mastodon.
