What's up!!! Sounds like some cool back end development you've got going!
Anywho- my name's Mason, and I'm awesome at back end development. I love CSS, HTML, PHP, Javascript, and pretty much any kind of code- I'm a nerd. I'd love the opportunity to create some new kinds of tech for your webpage (I even have a friend from Florida sitting across the table from me right now, teehee), and everything you listed sounds easily doable within my skill set. I'd love the opportunity to talk to you, and to learn a bit more about the project.
Thanks for your time Aline, I hope to hear from you soon!!
