• Wrote a series of tools in C to dynamically determine the schema of ISAM files, extract the data and load it in Oracle.
• Currently completing the tool set by wrapping it in shell scripts, mostly awk and the C-ISAM extraction tools I wrote, to run inside a Grails application and set of Javascript/JQuery pages to manage ISAM extracts and Oracle loads into the Oracle staging database that is used for ETL.
