hi devblock
#46 The idea here is.
Create a unique and memorable logo
combining the letters "D and B". you can see the concepts of intersection, integration to form a single element.
#54 The idea here is
Use the letters "d and b" as programming language.
The arrows placed in parentheses, double direction, give the idea of feedback and bidirectional communication.
The first #46 is more generic, while the second #54 is more specific.
Both work very well as a personal brand and describe what they are.
now
I'm working on the suggestions
I always think of the function logo, look good in different backgrounds, small size, printing, fax, social networks, new technologies iphone... etc
simple, memorable...
best regards
Fernando
