AboutSobre mí

About me

Freelance technical translator · Houston, TX

Before translating technical documentation, I wrote it and lived it: I worked as a systems programmer at IBM, a foundation that lets me truly understand the content I translate.

For more than three decades I have worked in professional English–Spanish translation. I founded and ran translation companies in the United States, and today I work independently, serving each client directly from Houston, Texas.

I translate into Neutral, Latin American, or US Spanish, depending on the audience your content is written for.
