Expert Web Scraper, Automation Developer - Web/Des...

India - Last active: 7 hours ago - Tests: 5 - Portfolio: 5

- Web Scraping/Crawling (using NodeJS, PhantomJS/CasperJS, CheerioJS, Python, PERL & Java) - General Automation (Web/Browser/Desktop) - Greasemonkey/Tampermonkey scripts - General Scripting (Python, PERL, Shell Scripting) - 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 I deliver 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). For clients who are interested only in the output, I’m by all means fine to run it on my set of hosts and give them the expected output (in the requested format - TXT, CSV, JSON, XML, XSLX, DOCX, Insert directly into a DB etc.). 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 Work Style? My approach for any fixed price automation job is - 1. Analyse the requirements 2. Come up with a time & price estimate & Review it with the client 3. Develop a quick sample script 4. Generate a sample output of the code and send it to the client for suggestions/corrections 5. Tweak the script to accommodate the suggestions 6. Develop a full fledged perfect script 7. Run the script to get the final output 8. Send the output (and/or script according to the job) to the client for a ‘thumbs up’ 8. a. By this stage we shouldn’t be having any changes in script, but if at all the client has any last minute changes, I can accommodate them, give a fresh run/output 9. Send any other related stuff - like README file, if the script needs to be run at the client’s end 10. Get paid & reviewed 11. If unsatisfied, I’m willing to give back all the money paid by the client. If at all you want to interview me, I’m available at Skype (ID: vdraceil) Looking forward to many great work experiences.

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

Poland - Last active: 7 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 ;)
