    Expert Amazon MWS, Laravel and Scraper Developer

    United States - Last active: 8 days ago - Tests: 3

    I'm an expert at PHP/Laravel, MySQL, JavaScript/jQuery, AJAX and Amazon MWS/AWS development backed by 13+ years of general coding experience. I'm familiar with a variety of marketplace integration APIs (eBay, Etsy, Google Shopping, etc) but my main expertise is with Amazon's MWS API. I'm highly skilled at automating processes for inventory listing/management and order/shipment data processing, as well as automated product matching (even by photo). I'm also skilled at integrating with DigitalOcean and AWS. I've worked with several development frameworks but my primary focus is on Laravel and AngularJS. The interfaces I develop to go with the underlying code are typically done in Bootstrap so they will be clean with an intuitive design (big fan of "Don't Make Me Think" style design principles). I specialize in automating websites by creating macros using GreaseMonkey/TamperMonkey. I am also proficient in the following: - Amazon's Product Advertising (formerly Associates/ECS) API - Inventory, order & shipment automation to/from diverse channels - Amazon Seller Central (including FBA processes) - RESTful APIs - Version control with Git and Mercurial - Creating web scrapers in PHP Goutte/CasperJS - Automating process of aggregating, manipulating and creating mashups of content I'm a rapid adapter so if any API or framework is outside of my present scope, I can usually integrate it into my knowledgebase/workflow on the fly in most instances.
