What I'm looking for

I’m looking for remote part-time or full-time work where I can evaluate AI outputs, correct transcripts, annotate high-quality data, and support NLP/ASR quality improvement. I thrive on detail, accuracy, and continuous feedback loops to improve model performance.

I’m an Economics and Business university student with 1 year of experience in AI training, data annotation, and AI model evaluation. I focus on detailed, analytical work that improves AI output quality through hands-on review and correction.

As an AI Trainer & Data Annotator (remote freelance, 2024–Present), I evaluate AI model responses, correct audio transcripts, and complete rich transcription annotation with linguistic accuracy checks. I also run AI model comparison tasks and assess Text-to-Speech quality, including TTS MOS evaluation.

I’m quality-focused and dependable in remote workflows—covering data labeling for training, NLP and ASR evaluation support, and quality assurance for AI outputs. I’m available for remote part-time or full-time opportunities as an AI Trainer, Data Annotator, AI Evaluator, or AI Content Reviewer.
