Senior backend engineer. I work on high-traffic distributed systems, and write about what breaks them.
I've been building backend systems since 2015 — mostly high-traffic, mostly the parts that are invisible until they break. Currently a senior software engineer at Toters Delivery, previously at Foodics and Robusta Studio. Most of what I write here comes out of that work.
