I am a Data/BI Engineer with 9+ years of experience designing, building, and maintaining data pipelines and analytics solutions in cloud environments. I have worked extensively with SQL, Python and modern data stacks (dbt, Snowflake, Azure) to transform raw data into reliable, production‑grade datasets used for reporting and decision making. While I am new to formal AI training and data labeling roles, my core strengths are data quality, systematic evaluation, and clear documentation. I am comfortable working with complex schemas, validating edge cases, and analyzing model outputs or metrics to identify failure modes and potential improvements. I am looking to leverage my strong data background to contribute to high‑quality training data pipelines for AI and ML systems.
