Design, develop, and maintain relational databases and software applications for NASA ground systems projects). I have been involved with numerous projects designing and creating Oracle, PostgreSQL, and SQL Server databases and applications. I have also designed and developed numerous applications and database access routines using Visual Studio .Net (C#), Java, Pro*C, Javascript, and PHP. One recent application I developed was a PHP application accessing a SQL Server database to store and retrieve metadata for archived data. This database is expected to reach 250 million records. Another application that I recently developed was a C# application that imported records from an XML file into a database. This application successfully transitioned approximately 500,000 records from an older application to a replacement application without any issues. On another recent project, I converted a C# application from a client-server application to a web application by replacing the SQL calls with web service calls allowing the application to be run virtually anywhere. Another part of this effort I transitioned the database from SQL Server to PostgreSQL thereby simplifying our database environment. The database design and development efforts have involved designing logical database models from user requirements, developing physical database models, creating and maintaining SQL scripts, developing database access routines, building and managing development databases, and supporting operational DBAs in installation, maintenance, and trouble-shooting. DBA support has involved, installation support, troubleshooting operations/user problems, leading Tiger teams to resolve operational problems, database/application performance tuning, strategic database planning. My application design and development activities include server-side and user interface development as well as database stored procedures.
