Eric is a life-long student of Chinese Mandarin and has worked as a Chinese Linguist for a good portion of his life. He wanted to create games and apps that help with keeping up his Chinese skills. He hated the hours he spent creating flashcards. “Chinese Mandarin Alpha Team” is one of many of his language learning games.
