Marco Paganini - Resume


In 2007 I joined Google, where I currently work. This resume is heavily outdated and doesn’t reflect details of my professional experience since that date. For further information, please contact me directly at paganini[at]paganini[dot]net.


I’m drawn to challenging positions in the field of Site Reliability Engineering, Systems and Network administration, Technical Management, and/or basically anything that keeps production services up and running.


Solid knowledge of Site Reliability Engineering practices, Unix/Linux system internals, networking, automation, and monitoring of high availability production systems (Google SRE since 2007).

Very familiar with many of the technologies and protocols used in modern production services, including containers, load balancing, clustering, HTTP, SSL, SMTP, DNS, TCP/IP, and many servers implementing them (Apache/nginx, various mail servers, bind, etc).

Fluent in a number of programming languages and frameworks, including C, Python, Golang, Shell, Javascript, and markup languages such as HTML, XML, YAML, etc.

I’m an author, heavy user, and a firm believer of open source solutions (whenever possible).
