    Recovering Journalist

    United States - Last active: 1 day ago - Tests: 3 - Portfolio: 2

    I am a seasoned communicator with extensive experience in large and small companies, in solo and team enterprises, in print and online and in tight or long-term deadline situations. Despite retiring from a 40-year career several years ago I still feel the urge to be creative. No job is too small, no challenge too big. The work portfolio contains everything from obituaries to pigeon racing, from an anti-meth non-profit to major college alumni and from teaching at the university level to volunteering with fifth graders. Because of the nature of my professional life, I have learned to be a very quick study and voracious researcher. I work comfortably with a variety of computer systems and software. And I am prepared to help you with your project. Send me an e-mail and let's talk about how I can help you.

    Petr B.

    Senior Developer, PM

    Russia - Last active: 1 day ago - Tests: 5 - Portfolio: 1

    I have strong background in UNIX/Linux software development, Master's Degree in Computer Science. I worked on Enterprise high-load distributed hosting automation systems as a Team Leader (3.5 years in SWsoft, Inc., now called Parallels). For the last 6 years I'm running my own small software development business in Russia with primary focus on Python/Django apps. Not pure Web but often involving integration with hardware (Proximity Cards, Sensor Screens) or external systems like Payment Processing, SMS Gateways, GABRIEL (Airline Reservation System), etc. I can take an idea and turn it into a working business, through all the intermediate stages. Also I have experience of investing my own funds in my projects, so I feel the difference between "perfect code" in a month and "good enough" code that increases the revenue right now. Nevertheless, my code is very good: no copy-paste, always written with performance, flexibility and security in mind, etc. On oDesk I'm looking for (and actually find :) interesting projects with a sight on long-term fruitful cooperation. I'm also open to smaller activities (e.g., consulting) where my knowledge can be helpful.

    Reliable Software Engineer specialised in desktop software

    Spain - Last active: 1 day ago - Tests: 8 - Portfolio: 1

    I have a degree in Computer Science B.Sc from the university of Manchester and was one of the top of my class in all of the programming courses (Java, C, C++, C with OpenGL) I have worked in the defence industry working on UAVs (aka Drones) and on the Julius Chinook helicopter and both of these were coded in C++ and Microsoft Visual Studio 2008. I spent a period of my time working on a legacy system written in Borlund C++ and converting it to a new system using Visual Studio. I also spent a period of time writing C in Eclipse on an embedded system (this was for the JULIUS Chinook project) I am extremely willing to negotiate on price and for English projects the language barrier certainly won't be a problem. I am extremely flexible and am always willing to work late or make additional changes or fixes as and when required. Fixes to problems can certainly be negotiated on price/time wise.

    4+ years of experience in filmmaking, editing and graphic design

    Greece - Last active: 21 days ago - Tests: 11 - Portfolio: 3

    *** Currently using the latest Adobe CC 2014 software *** BIO I am a filmmaker and freelance graphic designer. I have a diverse education, including film, graphic design and motion graphics at the Dept. of Audiovisual Arts of the Ionian University in Corfu, Greece. My focus is film. I am extremely interested in working on creative film and graphic design projects that need a fresh and modern character! My attitude towards working with clients is "create, get feedback, improve, get feedback, polish, deliver". I am very patient with clients and what I want most is the client to be satisfied with the final result. In my four-year working experience with clients, I've been creative, fast and cooperative. I do what I do because I love it. Creating things is my natural space. In graphic design, my original style is modern and minimalist, though I can achieve any look you need to get. I like to deliver customized creative solutions, and not just template copy-paste work. Highlights of my film and video work are available at www.georgetsirogiannis.com My full graphic design portfolio is available at www.be.net/amberturecreative Thanks!
