It all began when I was born, my parents spoke in Spanish and bam, I became a Spanish speaker.
Spanish is my native language.
Professional experience
Other than my day to day life with it, I actively use it to create articles on learning English (in Spanish) for the Interactivo. I have had to sit down and write blog posts, short concise answers for bots, and rules and explanations of our patented system.
I have also used it to translate English-Spanish and vice-versa. I have done written and spoken translation and have even done real time spoken translation a couple of times as a volunteer at church.
