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 400 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 Looking forward to many great work experiences.
