    I have a PhD from Harvard (philosophy) and a bachelor's degree (math and philosophy) from the University of Oxford. Professionally, I wear many hats: * Programmer: I'm comfortable with JavaScript, React, HTML, CSS, SQL. I've built an online store, interactive explainers, and web games. * Translator: I've published translations of Polish poetry into English, including by the "untranslatable" Miron Białoszewski. I have translated and edited philosophical texts by clients at the philosophy department of the University of Warsaw, to consistently glowing reviews. * Writer: A reader called my essay (about living in Senegal) “the most nuanced article [she’s] read on Medium.” I was a staff writer at Rabbit Hole Magazine.
