I improve AI models through RLHF, evaluation, research, and human-centered analysis.
BrazilWhat I'm looking for
I contribute to freelance AI training projects through RLHF workflows, response ranking, prompt interpretation, and structured quality review. I evaluate model outputs for reasoning, helpfulness, factual consistency, and alignment with project objectives.
My work supports human-in-the-loop processes that improve large language model performance, including annotation, data collection, and judgment-based tasks delivered against detailed quality standards.
Alongside AI work, I've conducted digital research and consumer-oriented analysis using surveys, user feedback, and market-focused tasks. I've evaluated websites, digital media, and online platforms for usability, relevance, and quality, delivering structured feedback to improve user experience and content effectiveness.
My psychology background includes clinical internships in health, hospital, and outpatient mental health settings, as well as nonviolent communication and bullying prevention programs. I also provide multilingual translation, transcription, business writing, and Adobe Photoshop services in Portuguese, English, and Spanish.
