Linux Administrator / PHP/Python Developer

My nameHi, my name is David Johansen. I am a young professional working in IT here in Phoenix, AZ. I specialize in Linux/Network administration as well as PHP, Bash, Python programming.

Personal & Professional Profile

I am looking for a position where I am able to organize and strategically automate processes with scripting and the use of open source technology.

I believe a well rounded Linux Administrator should also posses the development capabilities needed to work with complex applications and management tools.

My technical skills span across a wide variety of technologies and languages.

My strongest skill is in Linux Administration. I have completed my Red Hat Certified Engineer certificate, and most of my work over the past two years has been focused on Red Hat Linux administration.

I have also held the role of developing automation and monitoring scripts in python, bash, and perl as well as developing internal sites in PHP using MVC frameworks and MySQL.
