I work frequently with SQL and have a solid understanding of how to create web applications using the currently popular AJAX methodology.
My proficiencies are Javascript/Node.js/React.js/AngularJS, PHP, MySql/Oracle SQL, Coldfusion, C/C++ MFC & GNU, iOS, Android, and Linux systems configuration. Though I can make anything look and work fairly much how you want, my weakness is my eye for what looks good. So, so long as you have a good vision for what you want, we can accomplish fairly much anything together. I am willing to work very close with you to fine tune your product into what you really need.
I am willing and eager to experiment with languages that I am not familiar with and would be willing to cut a learning curve discount for lower priority projects.
