Federico Terzi

Senior Site Reliability Engineer London, United Kingdom

I run infrastructure for large products. When I do my job well, nobody notices.

cat about.txt

I'm a Senior Site Reliability Engineer with more than ten years of experience, mostly in fintech and large messaging platforms. Day to day I look after Kubernetes clusters and the stateful systems that live on them: ScyllaDB, Kafka, PostgreSQL, and the monitoring around all of it.

I manage everything as code, usually Terraform plus automation written in Go, Python or Rust. This site is a small Rust binary running on infrastructure I terraform for fun.

# uptime: 10+ years, no unplanned restarts
