Indonesian AI Trainer

Micro1Text
In my capacity as an Indonesian AI Trainer, I evaluated and rated AI-generated text using structured rubrics and quality guidelines. I generated and edited prompts and ideal responses, ensuring accuracy and contextual fit, and performed labeling for summarization and question answering. I used web-based platforms to assess and improve LLM outputs for safety, clarity, and policy compliance. • Assessed Indonesian LLM outputs and implemented prompt refinements. • Provided justifications to support score decisions on each sample. • Worked on RLHF-style and evaluation/rating language labeling. • Led efforts to improve AI text model quality and reduce bias.
