I have a bachelors degree in Accounting and am licensed as a securities respresentative. I have spent the better part of 7 years customizing spreadsheets and databases to perform specific functions.
I have customized applications in Excel, Access and other software programs for many different companies. A lot of my customization has been in the financial services and banking industries. I spend a good bit of time taking existing database structures and making them more accessible and understandable for users that are not database savvy. Integration of different file types into a database to create customized reports is a big part of what I do.
I have taken data sources with millions or pieces of data parsed that data down into a manageable subset required for specific tasks and reports. For a lot of people, MSSQL is not a db that they run on their local computers, but it is the DB that drives their web sites. For this I have done a lot of linking of Access to the MSSQL data
