    http://www.linkedin.com/in/morgwai I'm a deep-server-side guy specializing in scalability and high availability of large distributed systems. I used to work at Google for 3.5 years where big-data and no-sql terms were coined. Designing, deploying and maintaining large-scale, complex systems on Google cloud was my daily bread. I have a very good ability of learning new technologies and analysing existing systems. My work at Filemedic is a good example: when I started I knew nothing about Android NDK except that it allows to use native c/c++ libs in android apps somehow. A month later I created an NDK-HOWTO for advanced users, reported several bugs in NDK itself and fixed few myself of which at least one was critical.  less

    Experienced in all facets of web and system programming, including eliciting requirements, designing, coding and testing. I am an excellent communicator with an aptitude for explaining complex technical details to non-technical audiences. Since 2005, I have been in technical leadership positions in the software industry, where I've proven my ability to implement functional, maintainable software which users & clients love. I have a B.S. in Information Technology and a M.S. in Computer Science, so I'm equally well versed in theory and application. Technologies I use everyday: jQuery, JavaScript, AJAX, CSS, HTML, JSP, Java, SQL. I'm currently learning Python and Django, and am able to bootstrap on new technologies/concepts quickly. Just getting started on oDesk, but I'm interested in building a portfolio of work here.  less

    Since I remember I loved a web development. As a 10 years old kid I started learning HTML and I created my first simple website. After a short time, I extended my knowledge with javascript, css and php, to create more advanced pages. In high school I started creating small games in flash and action script. When I was about 16, I started learning java and C++ for creating more complex games and application. Now I am well experienced web developer. I use a wide range of technologies like PHP, javascript (preferable coffescript compiling to js), ajax, ruby, java, and of course frameworks for them (last time I loved java Play framework for web developing). I am also a passionate about android development.  less
