Freelancer Overview

I am a Senior Domain Expert (Psychologist, 17+ years) with a technical background in Web Development and Data Analysis. My unique hybrid profile allows me to specialize in RLHF (Reinforcement Learning from Human Feedback) and LLM evaluation for the Spanish LATAM market. Unlike standard annotators, I combine deep behavioral insight to assess tone, empathy, and safety (Psychology) with the structural logic required for code evaluation and data structuring (Dev/Data). I have experience cleaning datasets, designing logical workflows, and evaluating AI responses for accuracy, reasoning, and cultural nuance. I am detail-oriented, tech-savvy, and ready to handle complex reasoning tasks.

Executed a data structuring project for the UAESP Challenge (Advanced Level). I performed data collection, cleaning, and classification of large datasets regarding public services. Instead of manual entry, I utilized Google Sheets and Google Apps Script (JavaScript) to automate data validation and cleaning processes. Finally, I used HTML/CSS to structure the data presentation. The project required strict adherence to data integrity standards.
