About

Hi, I'm Clara Lehto. I have been building and operating backend systems for a little over a decade, most of it at small companies where "the infrastructure team" meant two people and a pager.

These days I work as an infrastructure engineer in Warsaw, mostly on networking, observability and making deployments boring. Outside of work I run a handful of self-hosted services for friends and family, which is where most of the material for this blog comes from.

What I write about

• Linux networking and kernel tuning
• nginx, TLS and the web stack
• Small-scale self-hosting done properly
• Profiling and performance in Go
