    VBA / Office Specialist

    United States - Last active: 1 month ago - Tests: 1 - Portfolio: 4

    I apply my knowledge of the wide range of IT technologies and processes I have encountered in my career to every new project that I am involved in. I have an innate ability quickly to see the most efficient solution to almost every problem that I encounter. I have saved my past employers both money and manpower with the solutions that I have created. I have worked as a programmer, systems analyst, a Windows/UNIX system administrator, app developer, database architect, process improver, mainframe maintainer, and general all around computer guy throughout my career. When I start a new project I put all of my attention and effort into it until the end because I feel that is the best way to serve my customers. I am always professional in my interactions with all my customers and associates. I have used MS Office to create numerous solutions to various issues in an enterprise environment. The most impactful are listed below. -Created a scheduling database to ensure that all mainframe jobs and other tasks were completed for daily batch and post-processing. This greatly cut down on errors and omissions that were done in the past. -Created a server and workstation application in MS Access for Dental Advisors to review disputed claims. This application worked with mainframe data extracts, an external pictures database, and an internal database. It also gathered input from two other departments. This brought the company in full compliance with regulatory and privacy obligations. -Created a billing database for Small Groups to ensure proper and accurate billing. This helped the company retain business and saved many man-hours of work monthly. -Created many macros for Word and Excel to help others automate repetitive tasks thereby improving efficiency in the workplace. I have created databases in Lotus Notes to store production history. This helped the company comply with legal historical requirements by putting the data in one repository. I designed and created a many-table database to hold mainframe data in order to streamline ad-hoc reporting. I wrote Cobol programs to extract the mainframe's VSAM data into multiple flat files for input into a DB2 database running on an AIX server . This allowed us to create new reports for Sales and others in hours instead of the company's standard of weeks. I was half of the team that was most likely the first VSE mainframe shop to run without a mainframe printer. We utilized a beta version of mainframe TCP/IP software to push reports to a network printer and/or PDF files for emailing. This greatly cut electricity and paper costs as well as an hour from the nightly batch.
