I created and validated over 10,000 structured data annotations of GUI-based workflows within an Ubuntu Desktop simulation for LLM training. My work focused on building datasets that enabled step-by-step procedural reasoning and accurate digital task execution. I established guidelines, ground-truth benchmarks, and quality control checklists to ensure high levels of accuracy and reproducibility in annotations. • Developed detailed instructions for annotation of digital workflow steps. • Delivered projects with a 99% accuracy rate to meet client and quality requirements. • Analyzed LLM outputs to identify errors such as hallucinations and incomplete reasoning. • Emphasized accuracy in state verification and procedural step labeling within simulated desktop environments.
