    Web Scraping Expert, Automation Developer - Web/Desktop(Linux,Win,OSX)

    India - Last active: 1 day ago - Tests: 7 - Portfolio: 6

    - Web Scraping/Crawling - using NodeJS(Request+CheerioJS), PhantomJS/CasperJS, Python (Scrapy/BeautifulSoup), PERL(Mechanize/LWP) & Java(HtmlUnit), Selenium (and making it headless with XVFB) - General Automation (Web/Browser/Desktop) - Greasemonkey/Tampermonkey scripts - General Scripting (Javascript, Python, PERL, Shell Script) - UNIX command-line tools, VIM Try me. You won't be disappointed. What have I got to offer? I’ve got some really good experience & expertise in automation (web & desktop - Linux, Win & OSX), quick scripting & general coding. You can always trust me with almost any automation/coding requirements (ex. unix command line tools, developing quick scripts, tweaking existing scripts, web scraping/crawling, creating APIs) at a fair price and a very quick turnover. When delivering a piece of code/script, I’ll make sure that it is professionally written (to the highest quality & efficiency) and that it has a proper README file (on using it in your local system/host). Exclusive Experience? Web scraping & web crawling are clearly a part of automation and just here in oDesk, I’ve scraped close to 300 websites (all types - static pages, javascript/AJAX heavy websites, CAPTCHA posing websites, IP banning websites etc.) and I’m pretty comfortable with this. About me? I’m passionate about coding and so I always keep learning something new or look around github for some interesting projects to contribute. To me all programming languages are just a set of syntax rules - anyone with strong DS & Algorithm knowledge can learn and master them in days/weeks. Preferred OS: Linux, Preferred Editor: vim If at all you want to interview me, I’m available at Skype (ID: vdraceil) Looking forward to many great work experiences.

    C, C++, Java, Matlab | Qt, CUDA, VST, Audio, DSP

    Poland - Last active: 6 hours 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 ;)
