Across data and AI annotation projects with Appen, RWS, and TELUS International, I reviewed and labeled digital content according to project-specific instructions. I worked with text, image, and video annotation workflows, applying guidelines to keep decisions consistent.

At MotherCAT, I prepared, cleaned, and reviewed datasets for analysis and reporting. I also performed data validation and quality checks, then developed reports and dashboards to support data-driven decision-making.

My work with geographic and location-based data involved organizing and interpreting information in GIS/CAD environments. I also have basic knowledge of drone/UAV data concepts and geospatial workflows.
