Freelancer Overview

I am an Excel and data automation specialist with over four years of hands-on experience creating, validating, and documenting complex spreadsheets for analytical and technical use cases. My background includes translating detailed natural language instructions into precise, reproducible Excel actions, making me well-suited for data labeling, annotation, and AI training data projects. I have worked extensively with structured datasets, ensuring high standards of accuracy, consistency, and documentation—key requirements for AI model development and automation workflows. My expertise covers advanced Excel formulas, PivotTables, data validation, workflow documentation, and changelogs, and I am comfortable collaborating with technical teams to deliver reliable, audit-ready data for machine learning and automation contexts. I am detail-oriented, fast to adapt to new tools, and thrive in independent, remote roles that demand precision and structured processes.

The project involved performing large-scale image labeling tasks for a machine learning dataset through Mercor. The primary objective was to accurately annotate visual elements within images to support the training and improvement of computer vision models. Tasks included identifying and labeling objects, drawing bounding boxes around specific items, categorizing images based on predefined classes, and verifying annotations for accuracy and consistency. The project covered a dataset consisting of several thousand images across multiple categories. Strict labeling guidelines were followed to ensure consistency, including adherence to annotation protocols, class definitions, and formatting requirements. Quality assurance was maintained through regular self-review, guideline checks, and platform-based validation processes to minimize labeling errors.
