SKILLS

  • UNIX/Linux

    90%

    UNIX-Like operating systems live at the heart of everything I do, mastery is paramount.

  • Python

    80%

    Python is the swiss-army knife of Systems Administration; 3.5 is my flavour of choice.

  • Chef

    25%

    Chef is a common tool I've used before, it works well enough that it doesn't break so I don't get to play.

  • SaltStack

    70%

    SaltStack is my preferred automation system; I have recently been contributing to the community formulas.

  • PostgreSQL

    55%

    PostgreSQL is my preferred RDBMS, I can configure it well but advanced SQL queries are something I'm learning.

  • MySql

    25%

    I've used MySQL enough to know how dangerous it can be.

Stuff i like

  • Automation


    I love making things that do my job for me.

  • Learning

    If a project requires me to use my scripting abilities, I own it! I enjoy learning languages and creating projects.

  • Programming/Coding

    One of my favorite things to do is code. I live to create small projects and have started working on bigger projects. I mostly make things using Python and sometimes use PostgreSQL, Redis and MySQL.

I can't wait to show you what I've been working on!
