    Laravel Expert

    United States - Last active: 20 hours ago - Tests: 2 - Portfolio: 3

    I’m a Laravel expert that is backed with 8 years of real-world experience developing great PHP web applications. I began developing with Laravel when version 3 was released in 2012. Since then I have worked exclusively with the framework on a daily basis, developing web applications using all major release versions (3, 4, and 5). During my career I have worked with many clients, from start-up entrepreneurs to the United States government. I share the same passion as my clients. In 2009 I founded RotorSpace.com, the first social networking site for helicopter aviation enthusiasts and professionals. RotorSpace was a tremendous success and was later acquired by Vertical Magazine (MHM Publishing). I’m very proud of what the site was able to achieve in such a short period of time. Having success as both an entrepreneur and a developer allows me to understand the amazing amount of work and passion that must be put into a project for it to be successful. Given my success I have been able to shift my focus to being the best developer I can be. I want to work with you to solve problems and bring your ideas to light. If you’re looking for a developer that’s truly an expert, driven by passion, not afraid to take on a challenge, and will be there with you every step of the way then look no further as I’m your guy.
