Hi
I don't have too much information about what you want, but I believe that I can help you if you are trying to implement a Meraki infrastructure.
I have experience working with the MX and MR devices.
As a plus, I work for a Cisco partner in Central America, so I own several certifications from them, We had a Meraki Demo infrastructure where I have learn a lot from them, that's because Meraki currently don't own a specific certification process.
I also have access to the Meraki support if we have some kind of information that we want to clarify with them.
If you want to contact me you can do it via private message.
Best Regards
