Freelancer Overview

I am an experienced AI Trainer and Data Annotator specializing in healthcare, instructional writing, and complex text evaluation. I’ve contributed to multi-platform AI training initiatives across Mindrift, Scale AI, Telus, and Data Annotation Tech, supporting large-scale SFT, classification, relationship mapping, content generation, and high-accuracy evaluation/rating tasks. My background in healthcare operations and clinical workflows allows me to create precise, context-rich prompts, case studies, and documentation that strengthen model reasoning, safety, and real-world alignment. I bring consistent quality, fast turnaround, and an expert ability to translate nuanced requirements into clean, structured, and reliable training data.

Users increasingly seek emotional support and mental health guidance from AI systems. These AI interactions are called affective conversations. Affective Conversation with AI: The user engages directly with an AI chatbot in personal exchanges. The user is motivated by emotional or psychological needs. The user seeks interpersonal advice, coaching, therapy, counseling, companionship, or sexual/romantic roleplay. The primary goal in this project is to ensure responsible handling of these conversations through appropriate deflection strategies and professional referrals to protect vulnerable users. We will focus on demonstrating empathy and appropriate deflection rather than attempting to provide direct support for vulnerable users engaging in affective conversations.
