    Graphic / Web Designer

    United States - Last active: 1 day ago - Portfolio: 1

    For 15 years, I have worked as a Graphics and Web Designer. I've done extensive work designing everything from CD jackets, poster boards, to magazine and book covers. For five of those years, I worked in my hometown of Tokyo Japan, under Tztom TODA design firm. I was also heavily involved in the design of www.rakuten.co.jp, the number one Internet eCommerce portal in Japan. My desire to experience and learn as much as I can lead me to America where I started designing websites. The San francisco Bay Area has been my home for the past 10 years and have enjoyed every moment of it. Most recently I've had the opportunity to design print materials for some of the fastest growing companies in the Bay Area. These print materials include folders, catalog sheets, business cards and even logos.

    Health Informatics Consultant

    United States - Last active: 7 days ago - Tests: 1

    I apply a solutions based approach to solving complex puzzles, and achieving successful systems improvement. I have a natural talent for "out of the box" creative strategies that solve complex puzzles. I love looking at systems and finding ways to improve them, and I also love using my conflict management skills, analytical abilities, critical thinking capabilities, and interpersonal skills to cultivate cross-cultural relationships. Today, this combination is more important than ever. The world is becoming smaller and smaller and people need to be able to reach across cultural divides to solve complex issues that affect the world we live in. Nowhere is this more true than in the healthcare arena. I am currently using my extensive experience as "problem solver extraordinaire" with the Laboratory Informatics Institute where I evaluate and develop training programs for apps in the SciCloud. I work hard to define requirements, plan implementations, and provide superior on going support/training so that you don't have to. I specialize in EHR, LIMS, LIS, HIS, and HL7 apps to name a few. I also specialize in things like regulatory compliance and auditing. I am a one stop solution shop for all your HIT problems. I have spent many years learning, practicing, and finally honing this unique skills set and now I am ready to solve your puzzle. You have a puzzle and I have a solution!
