I'm Mari. I'm a staff software engineer at Netflix, working across distributed systems, architecture, product design, and technical leadership. I write to understand the work: the systems, the people who build them, and what happens as both change.
This is where I keep what I learn: field notes on reading code and evolving software, essays about power and learning in technical organizations, poems, stories, and experiments you can run.
I grew up in Cuba, found my way through Uruguay, and live in California now. The longer story is on the About page.
