My job spans a lot of areas including web development, project management, system administration, and network administration. My favorite areas of focus in development are performance, optimization, and security.
Code-wise, I mainly work with PHP, MySQL, Python, Node.js, Grunt, and jQuery currently.
I also have experience with C#, NSIS, C, C++, Java, Visual Basic, ASP, and MSSQL.
I love working with open-source software. Linux is awesome.
