    I am an experienced and proficient web scraper using Python to obtain very large amounts of data from a variety of online sources. I do fixed-price work and have successfully pulled data from 100's of sites with examples being business locations, directories, public information, IMDB movie info, sports-reference stats, music charts, Forbes company rankings/info, ESPN player pages, Google search results, as well as hundreds of other queries of all genres. You can see some of my results via the data sets which are used on my big data quiz site, hugequiz.com. I have been able to retrieve data from articles, tables, lists, recursively via search results, from sites with AJAX/Javascript, and even when authentication is required. Any project you have I would be able to discuss and preview the site(s) which need to be scraped in order to provide you the output you are looking for in .CSV or other format.

This gives me insight regarding the solution journey in order to create minimal friction and discover points of improvements ✗Not every business is my client, though – some signs we might not be a good fit include: 1. ”Respect for others” is not a core value (We love working with awesome people we respect) 2. Illegal or immoral activity 3. The company is based 1st world country and not willing to pay what a 3rd world country proficient professional rate, geo-located salary can go both ways (also can’t do that in good conscience, it goes back to point 1) TESTIMONIAL "This is my big thank you to Marcio Fernandes who is a very intelligent young guy, a cooperative colleague with a keen eye on analysis with the right details. He really knows his ways to handle complex projects. As a project manager, he has always been very supportive to me. His contribution and enthusiasm were very welcome and led to some successful innovative cost saving (transportation cost area) projects. I heartly recommend Marcio for any business that is looking for a good, productive data analyst/scientist with a good mindset. I'm very confident in his future career. Keep up the good work, Marcio!"
