    Public Relations expert with 10 years exp

    United States - Last active: 2 days ago - Tests: 1

    I am interested in utilizing my experience and knowledge in the Public Relations fields of material creation and writing, press release drafting and distribution, event planning, media relations, brand expansion and management and if needed crisis communications. I have 10 years experience working at public relations firms small and large. My last position was Vice President at Ogilvy Public Relations Worldwide in Sacramento California. My responsibilities included managing the work on two of the largest infrastructure projects in the United States, the California High Speed Rail project, and a new state agency created to solve the states water problems the Delta Stewardship Council. For the California High-Speed Rail Authority, I managed 10 regional project segments and 72 regional consultants statewide. I was responsible for the review of all public materials to ensure consistency in messaging and presentations made publicly at various meetings taking place each week. Additionally, I managed the education and partnership outreach statewide for the High-Speed Rail project to ensure that the Authority was reaching all communities throughout the state and not just those associated along the project line. 

 Prior to Ogilvy, I worked at KP Public Affairs the largest lobbying firm in California, where in the communications division, I handled the day-to-day operations of several major clients. This included the strategic oversight and program implementation for a statewide coalition "Alliance for a 21st Century Water System" to build consensus around the need for new water storage. In addition to coalition coordination and outreach, I also handled the statewide media outreach on behalf of the coalition and Westlands Water District. 

 Additionally, I served as client leader for a renewable energy company siting projects throughout California, Invenergy LLC and provided media relations support and business and brand communications strategies for clients such as the California Small Business Association and PETCO. In shaping public policy in California, Mrs. Ratcliff was responsible for the statewide communications outreach on behalf of the California Mortgage Bankers Association when the housing crisis began to spur legislative actions against the industry. 
Prior to my work at KP, I worked for almost five years at Burson-Marsteller starting as an intern.

 I hold a Bachelor of Arts degree in Government and Journalism from California State University, Sacramento.

    Senior .NET Developer

    Romania - Last active: 19 hours ago - Tests: 6 - Portfolio: 3

    I am a senior .NET programmer with over 20 years of professional experience, mainly in back-end C# applications using SQL databases - web services and Windows services. I am very familiar with SQL data modeling and normalization up to third normal form. One of my recent accomplishments was changing an error-prone, manual process that was taking three days each month into an automated, five-minute scheduled task using MS SQL Data Tools. Unit testing and test-driven design are very important to me - I have a book on TDD available at http://www.amazon.com/TDD-example-Evaluating-expression-ebook/dp/B005TEN130 . I don't mind working on pre-existing code without tests but I generally insist on adding them to any code I change.
