Freelancer Overview

I am a Computer Science and Telecommunications Engineer with over three years of experience working with large-scale data in financial institutions. My background includes analyzing and personalizing customer experiences using tools like Adobe Analytics and Adobe Target, as well as building and maintaining ETL processes with Apache Spark and Scala. I have a strong command of SQL for data querying and validation, and I've developed dashboards in Tableau to visualize and interpret complex datasets. My hands-on experience with data pipelines and attention to data quality have given me a keen eye for detail, making me well-suited for data labeling and AI training data roles. I am passionate about learning new technologies and thrive in environments where accuracy and precision in data are critical.
