What I'm looking for

I'm seeking a freelance AI data annotation, media evaluation, or language data review opportunity where I can apply native Spanish, attention to detail, computer proficiency, and consistent guideline-following while growing professionally.

I'm a native Spanish speaker with advanced English skills focused on accurate language data review, media evaluation, and AI data annotation.

Through English for Call Centers training, I completed intensive English and American culture coursework and participated in customer-service role-plays involving billing, technical support, and customer inquiries. I built strong active listening, information handling, communication, and attention-to-detail skills while following structured guidelines.

I'm currently studying Web Design & Technology through Platzi, building web development fundamentals while continuing to learn new systems and tools. I bring Microsoft Office, Google Workspace, internet research, data entry, basic HTML/CSS, and a 40+ WPM typing speed to quality-focused projects.
