Freelancer Overview

I am an experienced Executive Virtual Assistant and AI Trainer with over 10 years of expertise supporting data-driven operations and AI projects. My background includes hands-on work with data labeling, annotation, and training data preparation, leveraging tools such as NotebookLM, Notion, and large language models to optimize workflows and automate processes. I have implemented Lean Six Sigma methodologies to enhance data annotation accuracy and efficiency, reducing errors and retrieval times. My experience spans multiple platforms—including Buildium, Dotloop, Podio, and Kartra—and covers domains like real estate, HR compliance, and business intelligence. I am skilled in using Power BI for data analysis, ensuring GDPR compliance during data handling, and developing standard operating procedures that streamline data-centric operations. My focus is on delivering high-quality, reliable data to support AI and business intelligence initiatives.
