I am a developer of fifteen years at a company that produces ERP software for the (primarily) United States' dairy industry. From early in my career I have extensive experience with RPG III + IV on IBM's iSeries (formerly AS/400). Today, the primary tool I use for development is a (self-proclaimed) ARAD tool from CA call Allfusion: Plex. I have been developing with Plex for the past nine years, deploying primarily to Windows servers with Microsoft SQL Server as the database server.
