One man IT Department, Software Dev, and miracle worker.
I manage all our IT systems from networking equipment to MS servers running AD, MSSQL, MYSQL, Exchange and file shares.
I also develop SCRUD apps for core business functions in C#.NET, VB.NET, Obj-C/SWIFT (iOS), and PHP/JS.
I handle very "random" tasks, I've assisted in building product and other marketing demos. With a high school intern we built our own smart conference room using Arduinos, a basic server to handle web requests to serial COM and an iPad. I've also done ALL the data wiring in this building, approximately 400 Cat5E runs and 3 10Gb fiber connections between closets.
Lastly, I handle things that probably shouldn't be my problem like phone repairs (both personal and company equipment), managing vendors/service providers like our ISPs and cell phone provider, and I'm managing an ERP implementation across the company.
