    Senior Developer

    United States - Last active: 23 days ago - Tests: 1 - Portfolio: 2

    I have a degree in Computer Science and have been working as a contract web developer for quite a few years now. I've worked in many languages and technologies over those years and, given the proper frame of mind and incentive, I'm perfectly fine with learning something completely new to get a project done. Recently I've been moving into iPhone and Android Development but have also spent a lot of time working with PHP, MySQL + Postgresql, Laravel, Ajax (Json), JQuery, MCV + Activerecord patterns, MongoDB/Map-reduce, Facebook/Twitter/Google social APIs and Twillo SMS APIs. Real estate is almost a specialty of mine: Specifically data-mining (including scraping) real estate information and working with IDX and RETS property feeds. In the past I've also spent a lot of time working in ColdFusion and with C++ COM objects. Basically a jack-of-all-trades full-stack developer.

    Freelance Graphic Designer/Digital Imaging Specialist

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

    I, Nicole M. Bowen have been a Product Graphics Designer at Techtronic Industries (TTi) as well as a Digital Imaging/Design Freelancer in Anderson, SC since December 2011. I graduated from Clemson University ('11), having received a Bachelors of Science degree in Graphic Communications, graduating Cum Lade in my class/#6 in my major, as well as receiving a Cooperative Education certificate. Recently I have started my own Etsy shop and am selling custom designed stationary specializing in Wedding Stationary. During my studies at Clemson University I have completed two full-time internships, worked as a freelance digital imaging specialist for the past 3 years, and worked part-time at a local student-run printing job shop. By working during my college years I was able to gain the relevant work experience as well as an extensive knowledge base for my major and future career. In addition to my classes and working, I also was a 4 year letter winning student-athlete and a two-time ACC Champion in both individual and team categories for Clemson NCAA Women's Rowing. Being part of Clemson’s Rowing Team taught me the mental discipline and time management needed in order to juggle everything as well as excelling in the classroom. In my spare time I eagerly want to learn about new industry trends and photoshop techniques in order to make my work more unique. I also enjoy spending as much time outdoors as possible with activities such as hiking, running, kayaking, and playing a variety of sports. Recently I received my AFAA Personal Training Certification and am looking to then certify in CrossFit and compete regularly with CrossFit competitions.
