RLHF
Prompt Response Writing SFT

Freelancer Overview

My experience in AI training data centers on hands-on participation in Reinforcement Learning from Human Feedback (RLHF) projects and rigorous model evaluation. I actively test, prompt, and benchmark a wide spectrum of LLMs and AI environments—including Claude, Grok, Google AI Studio, Opal, and Antigravity—evaluating outputs for logic, tone, safety, and complex instructional adherence. Additionally, operating with native Spanish and full professional English proficiency allows me to assess cross-lingual reasoning and localized context, ensuring high-quality, nuanced data inputs for global models. What sets me apart as an AI trainer is the operational rigor and structural mindset I bring to data evaluation. My professional background combines high-level operations management for U.S.-based tech companies with an academic foundation in interior architecture and UI/UX design. This unique blend of systems-thinking and design logic enables me to break down complex prompts, easily identify edge cases, and deliver meticulously structured, highly detailed feedback. I do not just evaluate text; I understand workflow optimization and system logic, ensuring models are trained with absolute precision

Technical Prompt Engineer & Bilingual AI Training Specialist (EN/ES)

Internal Proprietary ToolingTextRLHFPrompt Response Writing SFT
In this ongoing project, I author complex, domain-specific prompts in both English and Spanish to assist AI developers in evaluating underlying model mechanics, algorithmic efficiency, and coding optimization. Beyond standard Supervised Fine-Tuning (SFT) and output evaluation, I provide strategic structural feedback on program designs, specifically consulting on workflows for adapting and managing datasets utilizing Hugging Face and Git repositories. By applying a rigorous, systems-oriented approach to both prompt generation and data pipeline architecture, I ensure that the training data and the adaptation frameworks are optimized for high-fidelity, multilingual developer models.
