I would also add: Polish your Profile text. You indicate that you worked with "micro-level grammar and syntax issues." However, your Profile contains a number of problematic issues involving grammar and syntax. These are certainly not mortal sins, grammatically speaking, They are, however, errors of flow and style that, one might say, are at a "micro-level."
Your Profile as currently written is adequate and understandable, but its format/writing style does not [yet] provide clear support for the claims you make regarding your expertise.
