United Arab Emirates - Tests: 14 - Portfolio: 4

In the the winter of 2008 I started a heated debate with my friend Tom over how the internet is revolutionizing the way we work and socialize with one another. Tom was an executive accountant in an established multinational and I was a budding online freelancer with talents and skills that circled around copywriting, content writing, web copy, articles, e-books, landing page content & optimization, user interface design, search engine optimization, Social Media, Internet Marketing in General. To prove my point, the following day I signed up with Odesk and within the next couple of days I had bagged my first Job. My online freelance career was ignited. I was excited and thrilled as my wild imagination started to paint pictures of a life with no boss, no office and no cubicles. I was fascinated by the idea of living of my creative writing talents and skills. Since my first assignment two years ago I have grown a lot wiser with my expectations and a whole lot better at churning out creative, fresh and courageously unique content for my clients. Even though I have over 5 years of corporate experience, I am happy to have kissed the corporate life good bye and to be able to earn a living by doing what I love - writing. PS: Tom was laid off three months ago. He has realized that change is the only constant and we are currently trying to sell his accounting services online - today our shared desire for inspired ideas has made us inseparable and our enthusiasm is nothing short of infectious

DC always delivers. But don't take my word for it see what the press says…"A master of website copy. Rides the crest of a web surfing content tsunami".
