Ottilia Waneta

I’m a Database and Advertising Administrator with a strict focus on zero-error accuracy. Since 01/2020, I’ve handled high-efficiency data ingestion and categorisation across internal database systems, entering, verifying, and updating records while performing regular data quality checks.

I combine rigorous data validation and quality assurance with performance-driven strategies for paid search and digital advertising platforms. I also train and optimise machine learning models across text, image, and audio modalities using AI data annotation and multi-modal labeling, all while maintaining strict confidentiality and compliance on time-sensitive data pipelines.

Before this, I supported core HR operations for 01/2010–12/2019 as a Human Resources Assistant, coordinating documentation and reporting, assisting with recruitment/training, and streamlining payroll preparation by tracking, verifying, and inputting sensitive personnel data. I bring strong process discipline, attention to detail, and problem-solving skills to every workflow.
