Freelancer Overview

I am a detail-oriented Electronics Engineering graduate with hands-on experience in AI training data, data annotation, and evaluation. My recent roles include working as an AI Image Trainer and Evaluator, where I developed and assessed prompts, evaluated AI-generated images and text, and contributed to enhancing model performance across tasks like photorealism, infographics, and persona evaluation. I am skilled in Python, data science libraries (NumPy, Pandas, Scikit-Learn), and image editing, and have supported structured data pipelines for high-quality AI model training. My background in electronics, microelectronics, and ICT, along with strong research and creative writing skills, allows me to deliver clean, accurate outputs and adapt quickly to new AI and data labeling challenges.

A model is trained by inputting feedback across multiple axes in terms of how the model's image generation conforms to instructions, quality, and overall natural vibe of the image. Multiple images are compared all at once, which can range from a minimum of two to around 30+ in some rare instances when training image regeneration capabilities.

AI Personas are evaluated and rated if they conform to their persona descriptions. If not, user prompt and AI response rewriting are employed to reach an ideal state. Content provided by the AI is moderated with Tier 1 and Tier 2 sensitive guidelines, where Tier 1 violations are rejected and Tier 2 are proceeded or rewritten with caution. A group chat involving a user and multiple AIs were evaluated as well to test the capability of multiple AIs being consistent with each other and the activity description. Another is evaluating and testing an AI's capability to personalize conversation by using various signals tied to a user. On top of all, a preference ranking is done on two or more resonses, if rewriting is not necessary.
