I have spent a year and a half building, maintaining and updating a custom NetSuite integration using C# and WCF services. The integration included all order flows within NetSuite, including sales orders, purchase orders, return authorizations, item fulfillments and item receipts.
This integration also included SuiteScript. SuiteScript was used to export files to an external system. Both user event scripts and scheduled scripts were setup for this.
I am also well versed in the administration of NetSuite accounts and account setup.
