    PHP Developer, Consultant, Start-Ups

    United States - Last active: 06/30/2013 - Tests: 11

    Over the last 8 years I have developed a number of websites in HTML, PHP, and MySQL. Since a young age, I've been hacking away at code and coming up with better ways to do things. At the age of 14, I launched FusionXHost and created one of the first sustainable post2host web hosts. I have a wide range of skills working on a number of start-up companies and ideas. Since 2004, my company -- FXH, Inc -- has been providing a wide range of IT services all over the world and has severed as a springboard for a number of different start-ups. I have been the primary employee of FXH, Inc and generally do most of the work myself. I primarily focus on the technical side of start-ups and currently have an in-depth knowledge of PHP, MySQL, JSON, Zend Frame, RESTful APIs, and a number of popular third-party APIs (e.g. facebook, twitter, foursquare, etc). In addition to the coding side, I also work on server infrastructures using Citrix XenServer and Amazon Web Services. I also have experience with C-Corps, LLCs, and payroll accounting; both the state and federal filing requirements. I’ve been using Quickbooks since 2004 and very familiar with the software and accounting standards. In addition to the accounting, I’m familiar with the legal aspects of starting and running a company. I’m not an expert in these fields, but am a jack of all trades type and know enough in each area to be cost efficient.

    Senior Ruby on Rails Developer

    India - Last active: 8 days ago - Tests: 2 - Portfolio: 1

    I'm a senior Ruby on Rails developer with extensive experience in building high quality sites. My experiences range from building scripts and utilities that help in promoting (and understanding) client products to industry-standard scalable web applications that solve real-world problems. I like working on projects with a team that cares about the code that they write - I write readable, robust, heavily-commented code with modularity in mind. It's important to me to build long term relationships with clients, so I'm primarily looking for long term projects. I'm flexible with my working hours and am happy to work closely with any existing freelancers you work with. I am experienced with advanced Rails concepts like polymorphism, STI, Self-referential associations, Multiple Database connections, and so on. I prefer to do test-driven development using RSpec/Cucumber. My picks for common gems are ActiveAdmin, Devise, Pundit, Sidekiq, Draper, HighVoltage, OmniAuth, Capybara, Poltergeist, FactoryGirl, etc. As a result of the past work that I have done, I am really experienced with integrating several APIs together and writing scalable scrapers using either Ruby, or Scrapy (Python). I look forward to hearing from you!
