Creation of complex sites from scratch

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

I am working as a web developer for about 10 years. I have started with small freelance tasks and ended with complex web projects. I believe my strong point is ability to understand other's code. I have done many freelance projects involving modification of working projects and that required deep study of code that has been written before. Such a work usually harder than writing a project from zero. I also have wrote from zero two complex CMS with Perl+Mojolicious. One of my large achievements is a complex site written on Perl for a non-commercial international organization (see in portfolio). Last three years I am working on a large online magazine with elements of social network. This requires understanding of Perl, fastCGI, HTML, MySQL. I am constantly implementing new features and fixing bugs that remained from old programmers. I prefer writing in Perl, though I understand PHP and have done many projects with this language. Listed below are my skills: — MySQL — Perl — Mojolicious — PHP/HTML/CSS/JavaScript/jQuery — Nginx configuration — Basics of Linux — dotCloud and other PaaS deployment

I've used to work for Oracle Inc. creating the Java Development Kit and I'm have made more commits to the JDK9 project than anybody else. My main focus was to deliver Java port for Mac OS X, so I have great experience both with Java and with Objective-C. I've been an intern in Howard Hughes Medical Institute in USA, making math and predictive models for the neuroscience institution. I have 2 higher degrees: master in Computer Science and bachelor in Economics, both finished with the highest possible grade. A while ago I've lost satisfaction with the job at Oracle and decided to become a freelancer. My aim here is to find interesting tasks and solve them.

Poland - Last active: 4 days ago - Tests: 2

While studying sound engineering & acoustics and being a passionate programmer, so far I've developed some desktop apps(Java/JNI/C/C++) and one applet (Java & SQL), mainly based on speech intelligibility tests and designed for hearing impairment diagnostics & hearing aids fitting/comparison.My other software was for doing some extensive signal processing (for example, spatial filtering & beamforming with multichannel recordings ~ for my bachelors degree in acoustics) and other custom manipulation on audio data (C#, Matlab), but ~sound~ is not my only point of interrest. I like to code tricky stuff, not only sound-focused, and I'm familiar with other areas & API's like Qt, Direct3D, DirectSound, OpenGL, OpenAL, winmm or nvidia CUDA, so far due to my home-alone, hobby-oriented, non-commercial experiences. Always wanted to develop games/scientific applications/utils, but I'm open for any offer that could make the world a better place ;)
