    Seth W. Agency Contractor

    Business focused London based internet project manager & SEO expert

    United Kingdom - Last active: 12/01/2010 - Tests: 2 - Portfolio: 1

    Having grown up in a connected world (I bought my first modem aged 11, back in 1985, in the pre-web days) and having provided internet consultancy since 1994 I like to think I understand the 'net. I have set up numerous highly successful online business ventures, either as a co-founder, sole founder or technical team leader. These businesses have each gone on to experience rapid growth due in part to the technical foundations I have put in place. I have built up a large network of trusted and capable developers, having employed or outsourced to over 200 people over this time. I am able to implement IT solutions that truly work for the business - always with a business owners' eye on cost, profit, effectiveness and simplicity. I can bring massive cost savings to almost any business with IT requirements, whether through outsourcing to highly skilled overseas developers or through deploying technology to drastically save communications and labour costs. I am also adept at online marketing, and able to personally shape website and social network presences to get the most valuable, free traffic for your site. My personal technical skills include c#, SQL, Windows environments as well as mobile applications and web sites and all forms of online marketing including viral and video content creation. I'm new to oDesk as a contractor but am interested in talking to anyone looking for a serious, skilled, long-term partner in internet consultancy, project management and development.
