    Review High Level Design Documents from Systems Architects for accuracy and consistency. Use HLD's to establish Level of Effort estimates for Professional Services development.Trained Ericsson customer's development staff on how to develop custom features within the Ericsson (multimedia) Content Management System (CMS).Identify issues with custom CORBA Content Store application developed by the Ericsson Professional Services team and used to provision multimedia assets in a Content Distribution Network. Problems were associated with sending large (multi gigabyte) content files over the internet using FTP. Issues encountered included the firewall closing the idle control channel after an hour causing the transfer to fail. Abstracted the use of FTP to an interface to allow the use of an alternate FTP client package (moved from ftp4j to Apache Commons Net package). Implemented code to overcome this issue and advised local technical team on configuration.Implemented a SOAP proxy to resolve an issue between the producer and consumer of the service. The producer of the service had a bug that prevented it from returning a proper file name for a specific type of asset. The proxy when inserted between the producer and consumer corrects invalid data from the producer and fixes it in the returned XML.Created work flow templates for processing multimedia content and metadata within the Ericsson CMS application using the Ericsson WatchPoint Studio (Eclipse plugin).Document custom components developed by the Ericsson Professional Services staff for use by Ericsson customers.
