Objective
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.
Summary
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).
