About Tina Šajfar

📖 Summary

I'm self-taught, self-motivated, and self-managed. I'm not a serious person unless required and enjoy having a good time while efficiently doing my job or whatever task is at hand. I can multitask and learn new things with the best of them and I do not work well in a micromanagement type environment.Senior Linux Administrator @ Unix/Linux system administration for the Environmental Protection Agency. From October 2015 to Present (3 months) Developer @ I was an escalation point for 3 internal support and application teams. I developed internal tools in bash or ruby (1.8.7/2.1.6) with my team, as requested, and I was in the process of converting production scripts from ksh/bash to ruby. I was involved in proof of concept designing/testing on multiple projects and on multiple levels including, but not limited to, ETL (psql), technical documentation, and automation. HIPAA/PHIPA is heavily enforced. From January 2015 to September 2015 (9 months) Linux System Administrator | Platinum Services @ This position has been specifically designed to exclusively support a list of selected Verizon Terremark clients' unix/linux infrastructures, administrations, architectures, supported applications (ex: MQ/Tomcat/IHS/apache/etc) in a more in-depth manner throughout the environments. I created a complete guide to understanding and using Verizon's external DNS application that was passed out to all affected employees and provided as a go to reference guide, in depth training material, and published on our internal wiki. From September 2013 to January 2015 (1 year 5 months) Linux System Administrator @ I am responsible for resolving technical Unix/Linux/HP AIX, DBA level 1, and external DNS related tickets over Verizon’s cloud infrastructure environment. Support topics range from hardware issues/organizing remote hands, specific client application/services support, any Unix/Linux related operating system issue, general maintenance/patching, and administration. I execute customer/ACE submitted change requests to SOP. My DNS work mostly includes the addition/modification/deletion of zones and A, MX, CNAME, TXT records via a GUI, Best Ever Nameserver (BEN) with dig's here and there for verification/troubleshooting/zone dumps. I recently collaborated with a colleague to create external DNS training material for our team and I volunteered to help with internal document migration to a new uniformed wiki system. I received special training to be able to support a live trading/banking company who’s PR01 and PR02 alerts have an SLA of 30 minutes to 2 hours. All of which are business critical. From November 2012 to September 2013 (11 months) GTRC Engineering/Accounts Manager @ I was promoted to the title of manager for both level 2 engineering and level 2 accounts for the GTRC. I was responsible for a team of 3 (accounts) and a team of 12 (engineering). While managing I created new permanent trainer position to help ensure there was a continuous availability of training and to provide mentoring to my direct employees where they felt was needed. This was designed to maintain service level agreements in a predominately proprietary environment with high turnover. GTRC Level 2 Help Desk Linux Engineer I provided resolutions for procedural, process, information and technical problems via case submissions from Global Cisco internal employees submitted by phone or automated means (Remedy). My primary support areas consisted of Scalix Email System Administration, Exchange Email, newsgroups, mailers, send as permissions, and any other level 1 messaging related issue along with IBM Clear Case and a general assortment of user-level enterprise Linux (RHEL) troubleshooting. I was asked to do new hire training for level 1 “Front Line” employees and Level 2 Engineers. During this time I revamped many training documents/articles and created new presentations that I/others taught to the team. During my brief time as a manager, I was able to pull the engineering department out of a red percentage of cases resolved within the SLA to green. This was roughly a 20% increase in service level agreements met. I was fortunate to acquire an accounts team that was self-sufficient and required little attention in the way of managing. GTRC Level 1 Help Desk Windows/Mac I provided front line Help Desk support for Cisco's Global Technical Response Center in regard to general Windows XP, 7, and Mac issues with an emphasis on MS Office, Webex Connect, Cisco proprietary software, account management, and IP phone/Soft phone support. I was chosen to be one of the few team members to be trained to provide VIP support for Cisco Executives. From November 2011 to November 2012 (1 year 1 month) Gaming Supervisor @ Best Buy Mobile Store Manager Geek Squad Agent I was responsible for high volume customer service and technical support (mainly involving, but not limited to a wide variety of laptops, tablets, mobile phones, desktops, printers, mobile networking devices, software/driver install/configuration, network connectivity issues, and virus/spy/malware removal, and data backup/retrieval) as well as performing the diagnostic and repair or taking the correct action necessary based on product warranties. From July 2010 to November 2011 (1 year 5 months) Raleigh-Durham, North Carolina Area Tina Šajfar is skilled in: System Administration, Troubleshooting, DNS, Technical Support, Operating Systems, Unix, Linux, Linux System Administration, Cloud Computing, Bash, Remote Troubleshooting, DNS Administration, Unix Administration, Global Application Support, Windows XP
