Hi, my name is Daniel. I am passionate about IT and technology. I work as the IT Operations Manager at CSIS Security Group, where I have been employed since 2007. My favourite work areas are technical Linux work, network design and configuration, and all sorts of automation. I am a fast-learning self-starter. I deliver results and work efficiently. Give me one week with a testing environment and I can teach myself a working-level ability in any technology.

IT Operations Manager

2015 - Present
CSIS Security Group

I was a one-man Operations shop with limited resources, high technical debt and a crumbling infrastructure. Having reversed all that through smart time investments, the infrastructure is now above industry standards and the department has time to spend on nice-to-haves.

Network Administrator

2014 - Present
CSIS Security Group

An IT company puts extremely high demands on the networking infrastructure. I have a wide array of practical hands-on experience planning, designing, implementing and maintaining a highly secure, complex (yet elegant) and stable network infrastructure. I have worked with a multitude of different networking software and hardware vendors and can adapt to pretty much any scenario.

UNIX Administrator

2007 - Present
CSIS Security Group

Unix and Linux administration is as much of a full-time job as it is a hobby for me. I can set up, automate, maintain and debug systems with ease. Starting my first system administration job at CSIS Security Group was a dream come true. From the very beginnings of the company with systems-on-metal through to self hosted virtualization platforms and now in the cloud, I have a very varied and well-rounded set of experiences.

Technical Support

2007 - 2015
CSIS Security Group

Providing technical support for an organization is often an Administrator’s first and primary task. Technical support is the department’s outward face, and must always be court, professional and succinct. As systems provide essential services for the user’s daily tasks, technical support is a valuable source of feedback. How often is something broken? What is not properly monitored? Which systems are not intuitive enough? Where should more resources be mandated? All these questions can be answered from simple daily interactions through providing technical support. Even a simple question such as “Hey we were tuning systems X, Y and Z last night, could you please give feedback next time you log in?” give critical information back to the technician working on the other end of the wire

Volunteer Computer Nerd

2003 - Present
Various non-profits

I provide a limited amount of my services to various non-profits and help out friends and friends-of-friends in whichever way I can. These days, everything is handled through social media and freemium services, much more user friendly than a self-hosted solution, but sometimes a more advanced set of requirements lets me use my extensive skills for solving problems outside of work.
