I have been freelancing for a while now, writing in various formats and can provide samples of my work.
I have a good 20 years of professional experience in technology.
BTW, I hold two masters - an MBA and MS Comp Sc from San Jose State University (CA, USA), along with a Bachelors in Computer Science
The reason I gave my background is to demonstrate the depth in my writing skills.
My MBA/MS programs entailed a lot of paper writing/presentations and so did my work.
Please check my profile to know more or ping me.
Thanks
Vivek
