One thing people often do in resumes (to avoid the whole "I" thing) is to do bullets (which is why I wrote "Experienced working ...." Some verbs to start off with include (but are not limited to): * Developed... * Created.... * Implemented... * Instituted * Established... * Evaluated.... * Managed.... I don't think, personally, "I worked in a very tight schedule" is the best way to phrase it, no matter what the context. Anything that stops the reader and gives them an unfortunate visual should be avoided...especially in resumes! But I think you should do what you feel most comfortable with. :)
