What I'm looking for

I'm looking for remote data annotation or AI training data work where I can follow clear guidelines, maintain high accuracy, manage quality-sensitive tasks independently, and contribute reliable, consistent output.

I've labeled image datasets for AI/ML training through Remotasks, completing bounding boxes, segmentation, and classification tasks while following detailed quality guidelines.

I review and correct annotation work to keep data accurate and consistent, and I manage task volumes and deadlines independently in remote environments.

In IT support roles at Kingfisher Nest Hotel and Suites and The National Treasury, I performed backups, disaster-recovery checks, system maintenance, and end-user troubleshooting. At Kingfisher, my proactive maintenance helped reduce system downtime by 30%.

I've also supported digital workflows as a freelance virtual assistant, organizing files, calendars, inboxes, reports, and structured workspaces across tools including Notion, Trello, Asana, and ClickUp.
