    Web application development

    Poland - Last active: 03/14/2011 - Tests: 14 - Portfolio: 13

    In my over 10 years of web development adventure I developed many sites (some of my latest work is in my portfolio) and I grew addicted to coding. About 6 years ago, bored by PHP, I stumbled onto Ruby on Rails which quickly became my favorite tool. I developed 3 large applications by myself and coauthored at least 2 more.I enjoy writing JavaScript code for some time now specializing in jQuery library.For over 4 years I was working as Expert Webdeveloper for largest online auction platform in Central and Eastern Europe, where I share my jQuery expertise among fellow webdevelopers. Later I got promoted to CTO of citeam.pl project (daily deals app). In late 2013 I got another promotion, to IT Manager. I am interested in everything from server administration, Ruby on Rails, node.js backend coding, HTML5, CSS3, JS frontend development to IT leadership focusing on employee engagement.

    Rob Chambers

    Python expert and scientific software architect

    United States - Last active: 10/17/2012 - Tests: 2

    I'm a highly trained, expert engineer with excellent academic and industrial credentials. American, native English speaker. My degrees are in Mechanical Engineering, but I've found that my true love is software development. I love working on teams with other passionate and technically savvy people, but I have plenty of experience in management and report-writing. I am currently in the midst of long-term world travel, so I'm looking for quarter- to half-time freelancing work. I can work sporadically and long-term, but I can also settle down temporarily and put in very heavy hours when needed. I'm an expert Python programmer (5+ years experience) and I have several years combined experience in other languages as well (HTML/JS/CSS, MATLAB, C/C++). I am a full stack developer, with experience administering on-site and cloud servers, writing server-side and client-side software, developing complex and parallelized data processing algorithms, and implementing web- and desktop-based UIs. I have worked on many small projects where I am the sole developer, but I have also led 5-10 person teams to develop larger systems. As a mechanical engineer turned software developer, I have a special interest in working at the intersection of software with math, science, and engineering. Fields of interest: Biology, numerical simulation, algorithms, software development. Particular competencies: Taking ownership of solutions from conception to delivery... problem specification, algorithm development, software implementation, testing, and distribution. Skills/tools Python (including Numpy, Scipy, Pandas, Scikit-Learn, Cython, SQLAlchemy, Enthought Traits, Anaconda, IPython Notebooks, etc.). Web and Hybrid Mobile App development (HTML/JS/CSS; AngularJS; Cordova, Ionic), MATLAB (including many toolboxes). Experience building and administering Amazon Web Services (AWS) systems. Comfortable with Windows, OS X, and Linux.
