Hi ,
I am MS Visio expert and my daily work is more or less related to draw complex network architectures, software diagrams, Scada System layouts, Flow charts, Project Schedules, etc.. with more than 10 years experience.
I have experience with multilevel network system architecture, I am familiar with Cisco Switches, Routrs. Firewalls, etc..
I can share some drawings from my projects.
Thanks,
H
