I'm a dual-national US/UK Linux & Network Engineer providing enterprise solutions since 2001. Yes, "2001"- when I resigned from NYPD to emigrate from Manhattan's Upper East Side to move to England. Before becoming a boring IT contractor I served as a Task Force Police Officer in NYPD's Transit Bureaus and was a Sergeant in US Army Special Forces. I mostly work in the UK, but have operated as far afield as Northern Nigeria.
