Would greatly appreciate any feedback from native speakers on my Summary section of social network profile.

I'm a Project Manager with more than 10 years experience in Project Management and over 15 years working experience in Telecom industry. I've worn many hats in my career and I know how things are done at various organizational levels.

Have you ever been delivering complex technical projects without facing any impediments, glitches, mishaps? I bet you haven't. Neither have I. I came across some of them when I had been helping my company's client, the nation’s leading mobile operator, to deploy IP network across hundreds of cities and towns. Thus we have enabled the client to launch a new business and become country’s No. 1 service provider.

In recent years, I've managed a broad range of technical projects of different size and complexity and I've learned some lessons which I'm ready to share.

Thanks in advance!
