Freelancer Overview

I have hands-on experience in data labeling and AI training from my work with Moon Valley Company, where I annotated datasets for machine learning applications such as image captioning and object detection. My role involved creating precise bounding boxes, crafting detailed image descriptions, and conducting rigorous quality assurance to ensure the accuracy and consistency of training data. I collaborated closely with cross-functional teams to preprocess and structure data for optimal model performance, using advanced annotation techniques that improved the usability and precision of AI outputs. What sets me apart is my ability to merge technical execution with strategic context—drawing from over a decade of experience supporting startups and working in digital innovation. My strong attention to detail, consistency in labeling, and understanding of how AI models learn allows me to contribute high-quality training data across sectors like computer vision, business strategy, and digital marketing.

Labeling Experience

Image Captioning & Object Detection for Deep Learning Models

Internal Proprietary ToolingImageBounding BoxClassification
As a data annotator for Moon Valley Company, I worked on a large-scale computer vision project focused on training AI models for image understanding. The scope included accurately labeling thousands of images using bounding boxes for object detection and writing clear, consistent captions for image classification and generation tasks. I maintained a high standard of annotation precision through multi-step quality assurance processes and consistency checks. My work helped improve model performance, usability, and training efficiency across multiple model iterations. The project was collaborative, involving close work with data scientists and engineers to align on annotation goals and dataset structuring.

Annotating and labeling text data

Internal Proprietary ToolingText
During my time working with an Edtech for about 8months, I was involved in text annotation projects that contributed to training and refining their AI models. The role required a combination of attention to detail, consistency, and an understanding of natural language patterns to ensure the data used for machine learning was both accurate and reliable. My key responsibilities included: Annotating and labeling text data according to project guidelines to help the model understand context, sentiment, intent, and entities. Ensuring accuracy and consistency across large datasets by following strict annotation protocols and performing quality checks. Collaborating with the team to clarify edge cases and ambiguous text samples, ensuring that the annotation scheme was applied correctly and uniformly. Providing feedback on annotation guidelines to improve clarity and efficiency for future projects.
