Confidential, Charlotte NC

Unix/C# .NET developer

Responsibilities:

• BigData project. Feeding Hadoop cluster from Microsoft SQL Server and Oracle databases in a daily basis and Streaming data from Bloomberg.
• Improving the security of 1,000+ jobs using CyberArk (ID VAULT). Current programs read credentials from different sources as databases, text files, configuration files, and properties files. All these credentials must be converted to “connection strings”. All the programs that read these credentials with authentication purposes must be changed to continue processing the current values and the mentioned “connection strings”. When a program (Unix Shell Script, Java, or .NET) reads a connection string, it must send it to CyberArk in order to retrieve the stored credentials in the VAULT and pass them to the calling program to grant or deny the access to any protected resource.
• Migration of 1,000+ jobs to new Windows/UNIX servers
• Migrated a UNIX application from Solaris to a Linux server. The application used a Microsoft windows service to connect to a remote vendor supplying trade information
• Created scripts to verify deployment processes
• Created scripts to search strings in Subversion Repositories
• Created automated test scripts to validate key Vanguard trading process.
