Web Developer

Switzerland - Last active: 7 hours ago - Tests: 10 - Portfolio: 9

Over the last five years, building up on my experience of information systems, relational databases, and Object Oriented Programming, I have developed and maintained proprietary web applications combining a PHP or JSP backend, rich media, and responsive frontends using HTML5, CSS3, jQuery, Bootstrap, Backbone, as well as a number of other frameworks. I have also worked frequently with either Java or Adobe Flex, on both the backend and frontend. I am completely fluent with either Drupal, or WordPress, and have developed and marketed premium items for the WordPress platform. I also have experience with more specific environments such as Facebook, Android, or Google App Engine. My primary competence lies in complete end-end management of web development projects, and leveraging the power of distributed systems to offset your costs, while increasing the efficiency of your organization. I want to build the web or mobile application you, or your business has been dreaming of. Because I can.

India - Last active: 2 days ago - Tests: 5 - Portfolio: 5

- Web Scraping / Crawling (using NodeJS, PhantomJS & CasperJS , Python, PERL and Java) - General automation (Web/Desktop) - Greasemonkey scripts - 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.

Well before the World Wide Web was a common phrase as it is today, before most people even owned a home computer I was programming code in a variety of languages for a variety of network related projects back when you had to put the handset of a telephone on a 300 baud modem. Trillions of lines of code under my belt and a mind that functions like a computer processing unit I not only understand today's most popular programming languages, I know how the languages themselves came to be. I am an expert who has owned, operated or worked with thousands of technology based businesses over the past 25 years. More than a programmer, I am a valuable consultant to any business wishing to build or improve any online enterprise. My work is relatively fast, accurate, functional and most importantly well constructed based on your exact needs. I do all of my own work but will bring in experts if necessary to accomplish the goals of your organization. I am an American living in Pennsylvania.
