Summary of Qualifications

Expert in Unix Networking and Systems Administration with a long term and comprehensive experience in design, implementation and administration of technical operations environments. I have extensive experience with highly available, mission critical, public facing sites. I am also proficient with secure practices, email, DNS, server provisioning, configuration management, monitoring, capacity planning, change control, business continuity and other aspects of technical operations.I recently took a hiatus from my engineering career to create a small company focused on artistic creations.

Employment History

I started a very small company on a shoestring budget and formed a team to design and build a luxury custom electric torch ('Flashlight'). Essentially a sort of jewelry.

Most significant achievement 

Linux/Unix Escalations Engineer 

Verizon/Terremark - Cary, NC March 2013 - Nov 2014

I provided senior level escalation support for Unix systems. This primarily included return to service activities that could not be resolved by prior support levels. I also handled a variety of escalations for related issues with DNS, network, storage & backup. A focus was placed on identifying and eliminating recurring issues as well as training and mentoring junior level support staff. This included working together to resolve issues as an alternative to escalation. The results were incident reduction, improved MTTR and improved 'first touch' resolution. 

Return to service tasks consumed no more than 50% of work time, often considerably less. Other regular tasks included creating and maintaining standard operating procedure documentation, detailed change instructions and requests, detailed post incident root cause analysis. Provided Unix SME guidance and participatio  in phone bridges during high impact/severity issues with executive visibility. Worked with account teams (Service Managers, Account Customer Engineers) directly facing customers to resolve problems and suggest and support migrations and upgrades.
