When writing short texts, usually detailing something I have done, I tend to not use the "I" pronoun in front of verbs, usually in front of past-tense constructions. Have seen it in emails from an indian professor and thought of it as an advanced speaker practice. However, I don't think I've seen this done elsewhere and have never before questioned it's correctness. Is is wrong?
Usage example:
Have looked through all the available files these past hours, but haven't found anything of particular use.
