I would trim the top line to something like this:
Network Specialist serving as an expert consultant on both Local Area Networks as well as Storage Area networks.
No need to abreivate.
Your first bullet point mixes both network architecture with systems architecture, something that you dont mention in your summary. Just something to consider.
Your other bullets may be a bit too technical for any of the non-technical screeners, just keep that in mind too.
I would not put "1 bullet point" job summaries. If anything take the above advice for the first bullet point and then elaborate on some specifics. You should have these if you have an consulting background in LAN/WAN networks. Something along the lines of "Set up Local Area Network for 50-60 computers". Just a vague example.
