    Senior Full Stack Developer (Mobile, Web, Script/ Utilities)

    United States - Last active: 14 days ago - Tests: 4 - Portfolio: 15

    I have 10 years of experience in both web and mobile software development as well as script and utility programming. My current main area of interests is within Data Science including data mining/scraping. I have several years of experience in writing screen scrapers for online data sources (scraping in total more than 500 sites). I will be happy to craft a state of the art product for you using the following techs: Bootstrap, AngularJS, BeautifulSoup, Scrapy. I am familiar with many others, but these are my favorite. WEB BACKGROUND I have wide knowledge of many modern technologies in web development stack -- from low-level networking protocols and system tweaking (debian, nginx) to server-side programming (PHP, Node.js, MySQL, MongoDB, Redis) to client-side programming (HTML5 APIs, Javascript, AngularJS). I could solve the programming task of any complexity for you. I prefer developing complex and unique web services and/or user interfaces rather than creating simple websites which are similar to each other. MOBILE BACKGROUND I am the Owner and CEO of a digital development firm, ebork Developments, LLC, which specializes in the development of mobile applications across all platforms (see below). Strong .NET, Java, Objective-C, and Swift programming skills including low-level performance optimizations and memory management. I not only know how to make an application work, but also know how to make it work fast and smoothly. Good knowledge of Android, iOS, and Windows UI patterns and guidelines. I can prototype any application UI for you. SCRIPT/ UTILITY BACKGROUND I have been writing data scrapers and other data intensive scripts/ utilities for many years. My language of choice for many of these is Python. However, I can successfully develop a utility in many scripting languages, including: PHP, Ruby, Perl, etc. I have written screen scrapers for over 500 websites, including Google Search and Craigslist. I have a very high working knowledge of HTML, which helps me quickly write any screen scraper you find yourself needing.
