Freelancer Overview

I am a data modeling and AI training data specialist with extensive experience designing and implementing end-to-end data labeling frameworks, annotation schemas, and quality validation processes across healthcare, insurance, telecom, and logistics domains. My expertise spans developing ML-ready data pipelines, managing large-scale training datasets, and ensuring high-quality, bias-mitigated labeled data using tools like Label Studio, Amazon SageMaker Ground Truth, and active learning frameworks. I have led cross-functional teams to architect robust data governance strategies, integrate metadata management with labeling standards, and optimize workflows for supervised machine learning projects. My strong background in SQL, Snowflake, PowerBI, and data modeling tools such as ERWIN and PowerDesigner enables me to deliver reliable, compliant, and actionable datasets that accelerate AI and analytics initiatives.

Labeling Experience

Enterprise ML Data Labeling & Governance Framework – Transportation & Logistics

LabelboxImageBounding BoxText Generation

I led the design and implementation of enterprise-scale data labeling and governance frameworks to support supervised machine learning and LLM training within transportation and logistics. My role involved building practical annotation schemas, entity taxonomies, and classification standards, and working closely with data science teams to create clean, reliable ML-ready datasets supported by clear guidelines and strong inter-annotator agreement (IAA) metrics. I developed automated validation pipelines to monitor label accuracy, bias detection, and dataset integrity, while integrating metadata management to ensure full traceability and compliance. Using Label Studio and Amazon SageMaker Ground Truth, I managed scalable annotation workflows, supported active learning, enabled human-in-the-loop refinement, and contributed to RLHF-style evaluation and fine-tuning efforts. As a result, we significantly improved training data quality, reduced labeling inconsistencies, and strengthened over
