    Fullstack developer with inclination towards non trivial problems

    Poland - Last active: 2 days ago - Tests: 9 - Portfolio: 1

    I am a wizard. Seriously. I use rare combination of talent, skills and hard earned knowledge and experience to solve others' unsolvable problems. Wonders and miracles done immediately, impossible stuff with minor delay. Upwork is an opportunity to learn more, faster, and get myself involved in much more interesting, diverse projects that I would thought possible previously. Such cases were, for example, helping Panama based company OSOP with systems they use to predict (and provide warnings for) earthquakes in mid-America region; or a web crawling problem that was neglected by everyone passing through the Chegg Courserank project (creating the general solution for this took me to senior engineer position... and further, to team management); lately I was able to provide candidate and code reviews and design basic specifications for entirely novel software - and surely, such contracts showed up as well. You can see some of my previous private/hobby projects on github: http://github.com/zencodism ... and some social programmer activity at stackexchange sites under the same 'zencodism' login. So far, I've created numerous utilities and scripts (C / C++ / Python), a complex image manipulation and postproduction suite (C++ / asm / CUDA, worked on this as a member of a team), some visualisation software: for custom equipment (Java) and voice emotion recognition (Node.js), and a few web based projects (Python with Django, PHP, Perl, Groovy - working with a team on huge CRM system) including also long team Java-based web scraping suite I both developed and managed the team involved. Further down the road I'm turning to web applications along with their server counterparts - everything from designing communication protocols with cryptography and some redundancy to a space simulation game I'm writing as a hobby. I can work in and administer various operating systems (Windows, Linux, *BSD, Solaris... this came in handy lately when web development job turned into disaster recovery of remote server), use several databases (mySQL, PL-SQL) and quite a few programming languages; even created one myself, just for fun. What will be next, may be up to you. Feel invited.

    PHP Web App Developer: Any Framework, APIs and UI. 15+ years (USA)

    United States - Last active: 6 days ago - Tests: 6 - Portfolio: 12

    Since 1998 I have developed dozens of web applications focusing on a wide-range of industries including custom search engines, affiliate marketing, real estate solutions and worker safety. As an autodidact, I pride myself on learning new technologies and continually improving my skill-set. As a freelancer, I believe in professionalism, clean code and representing my craft to the highest degree possible. On the server-side, Laravel is my current PHP framework of choice, although I am comfortable working with Zend, CodeIgniter, Cake and Yii. For the database layer, I have 14 years of experience with MySQL. On the client-side, I prefer jQuery, Backbone and Twitter Bootstrap. Although I am not a graphic designer, I know my way around the Adobe software suite. I write standard compliant HTML5 and CSS3. I have an eye for useable, clean and obvious functionality. I have experience with many APIs, including Amazon, Box.net, Infusionsoft, Facebook, Twitter, PayPal, eWay, Authorize.net and Google. I can write APIs from scratch and give your application a RESTful interface. I am seeking opportunities to build custom web applications from the ground up or taking an existing code base and improving upon it.
