KenyaWhat I'm looking for
On remote freelance projects, I annotate and process image, audio, and video data by applying detailed project guidelines. I review records for errors and inconsistencies, make appropriate corrections or classifications, and perform quality checks before submission.
In freelance data entry and validation work, I organize spreadsheet records, check for missing or duplicate information, and reconcile data across formats. I’m particularly interested in AI benchmark and evaluation projects where accuracy, error detection, consistency, and data integrity matter.
