I'm Mari. I'm a staff software engineer at Netflix, where I work on consumer identity — the systems that know which device is yours, which session to end, which of two hundred million accounts just signed in. I've been writing software for fifteen years and poems for longer, in two languages (a veces en las dos a la vez).
I learn by building, so most of what lives here is something you can read, run, or play with: essays on debugging and distributed systems, poems, stories, the occasional talk. The engineering and the poetry come from the same hands, and I stopped keeping them in separate rooms.
Cuba → Uruguay → United States. California, these days.
