In a little more detail...

Have a background in physics and computer science. Since then have caught the language bug so love studying foreign languages. Primarily that has been Asian ones, but also have dabbled in Russian and Arabic.

Interested in making apps that help increase the rate of language acquisition (still have the goal of speaking 5 languages).
