Freelancer Overview

I have hands-on experience in data labeling and AI data training through roles with Data Annotation.Tech, CrowdGen, OneForma, and Outlier AI. As a Freelance Translator and Data Annotator, I contributed to refining AI language models by reviewing, correcting, and enriching linguistic data in English and Spanish, primarily. I ensured high annotation accuracy and applied contextual judgment to improve model understanding, consistency, and cultural relevance. My work directly enhanced the performance of AI systems by integrating nuanced language patterns and addressing edge-case language phenomena. I also have a multidisciplinary background that combines data science, translation, sales, and business intelligence. I hold a certificate from the TripleTen Data Science Bootcamp and am proficient in Python, SQL, and machine learning, which enables me to bring analytical rigor to data labeling tasks. My ability to merge linguistic expertise with technical skills, along with a proven track record in multilingual environments, positions me to deliver high-quality, context-aware data that drives AI model effectiveness.

Labeling Experience

Babel Language Project

OneformaTextClassificationQuestion Answering

This project involved evaluating English and Spanish prompts and their responses for Context and Correctness. The translated prompts and responses (in Spanish) had additional parameters, such as fluency, meaning retention, grammar.

Static Steerability - Personality AI Personas

Scale AITextEmotion RecognitionEvaluation Rating

This project involved making sure that the model responds according to the assigned AI Persona role. We would classify two responses across some parameters and rate which one is better.

Bilingual Data Annotation

Data Annotation TechTextClassificationQuestion Answering

This project involved generating prompts in 6 categories (Open QA, Closed QA, Summarization, Creative Writing, Structured Data Generation & Role-play) and evaluating the two model responses in 6 areas (Localization, Harmlessness, Context, Correctness, Prompt Category, Response Rating) to choose one answer over the other. In several cases, rewrites were needed to improve the models' capabilities in English, Spanish and German (least worked language).
