About Sacha Ligthert

Introduction

Hi, I am Sacha Ligthert. A 30+ Systems Administrator from Amsterdam.

During the day I work at The New Motion B.V. to beat anything in submission that comes my way. This ranges from faulty EC2 instances, running docker containers running in DC/OS, dealing with AWS oddness and the rare wifi network.

During the evening I am doing most likely one of the following things: Exploring new technologies Playing video games Hugging my wife Making time-lapses of random processes
