SUMMARY:

• To obtain a career with a company that offers the opportunity for me to use and develop my skills.
• I was assigned a fortune 1000 customer that had given the company poor marks in feedback for their inability to resolve their numerous technical issues.
• Within 6 months that same company gave very high feedback to me for fixing most of their issues and the company was able to use them as a reference for new customers.
• I architected a solution where I consolidated 5 Exchange servers that were located in different parts of the world into a single implementation of 4 servers that were high availability located in 1 central datacenter.
• I migrated 10 Exchange servers for a single organization from their old hardware to new hardware.
• This was done as a tech refresh but also to resolve technical issues with the original implementation.
• I have served as a primary escalation point for my teams in the last 3 companies I have worked for in Active Directory, Exchange, DNS, and connectivity issues.
• I have personally written over 150 KB or Knowledge Base articles to aid in troubleshooting and provide step by step instructions for other engineers in areas where I either had specialized knowledge or was disseminating custom information.
• I learned Sequent (an old version of Unix used by 4 customers in the world now) when I was asked to by my company.
• The Unix team would not do administration for it because it was so old so I was tasked to not only learn it but to administer it and write KB articles so that other engineers would be able to do administration in my absence.
