    United States - Tests: 2

    I am a seasoned database and system administrator with over 20 years of experience. If you're looking for simple stand alone programming or strategic enterprise implementations or anything in between, you've found the right person. I have developed and maintained various applications using Microsoft Access and VBA. I've been fortunate to take part in many enterprise level software implementations including Computerized Maintenance Management Systems (CMMS), Laboratory Information Management Systems (LIMS), Geographic Information Systems (GIS) using ESRI products, and PeopleSoft Systems (HR and FSCM). My part in these projects included both technical and project management duties. On the back end I sized, installed, and configured the UNIX (AIX, Solaris, and Linux) and Windows servers. I installed and configured the Oracle databases for these applications. Oh and of course, production maintenance for all the above is also included.
