MySQL is the long term standard when it comes to relational databases. Having utilized it in nearly every API service and website build since 2007, I can offer insight into every angle of MySQL usage. From inner and outer joins to updates and select queries, along with installs, backups, and scalability, all aspects of MySQL can be explored.

PHP is the swiss army knife of web development allowing rapid development of any number of online services, whether RESTful backends or simple front and back end builds, PHP and the multitude of tutorials, libraries, and frameworks, mean developing nearly anything on it is never hard. The original language of choice for Facebook, among many other high visibility websites, it doesn't look like PHP will be going anywhere fast.

AngularJS has been a breeze of fresh air when it comes to the javascript front end development world. Finally allowing backend RESTful services to be 'glued' to the DOM in an convenient fashion. 5* to google. Personally, I have utilized AngularJS to create a number of web apps, including an event booking system, a dating app, and a social media content sharing system.
