Richard C. Agency Contractor

Web and Mobile Developer, DevOps Engineer, Strateg...

United States - Last active: 07/14/2014 - Tests: 1 - Portfolio: 8

I have worked as a Senior Software Engineer and Technical Lead at several large and well-known technology companies and know the inside details on managing large-scale, high-volume web applications. I develop super smart, RESTful Ruby and Rails applications, and design elegant front end user experiences, using AJAX and Javascript frameworks to make applications faster and smarter, shifting logic from the server to the browser, saving you money on bandwidth costs. I roll out the red carpet for clients, and walk them through every part of the process. If you need a complex system with APIs built using AWS and complex load balancing and scaling issues taken care of, I will do it. If you want a Platform-as-a-Service solution for a simpler application that you can scale yourself without the need for a developer in the future, I can completely set this up, too. I build responsive designs which work on all devices (desktops/laptops, phones, tablets, and beyond), so your site is future-proof. I also design and build native mobile applications for iOS and OSX (iPhone, iPad, Mac, etc). I am also highly skilled in network security, having learned the nitty gritty of server administration and cloud services administration in Big Data real world environments–so your data is safe, whether it's a standalone booking system or a suite of apps sharing a common PCI-compliant billing system. My legal background also helps me assist with any jurisdictional, tax, or other concerns that may impact core design. Simply put, I take my real-world experience at large software companies and offer it to you so that your bright ideas become reality (and most importantly, they are done correctly the first time).
