Highly accurate and detail-oriented Data Annotator and AI Trainer with a strong ICT foundation and proven experience executing high-quality data annotation pipelines across complex computer vision modalities. Specialized in frame-level video segmentation, 2D/3D tracking, and dense multi-modal captioning. Experienced in evaluating model outputs for edge-case errors, verifying factual accuracy, and collaborating within managed production workflows to deliver highly precise datasets that train next-generation multimodal and autonomous AI models.

Video Data Annotator & Computer Vision Specialist at Mindy Support (2024-01 – 2024-06)

• Executed precision frame-by-frame video tracking, utilizing bounding boxes and semantic segmentation polygons on the Encord platform to label complex spatial environments for advanced robotics and computer vision models.
• Authored dense, logically structured text captions and temporal timestamp metadata detailing specific visual actions, environmental context, and object interactions within raw video datasets to eliminate model drift.
• Reviewed high-volume video annotations for pixel-level accuracy discrepancies, documented non-obvious edge cases, and maintained a >98% accuracy score against evolving client-side labeling guidelines.
• Maintained consistent production metrics and met stringent project turnaround times within a structured Google Workspace environment, reporting directly to project admins and QA team leads.

AI Trainer & Data Annotator at Remotask and Outlier AI

• Evaluated AI-generated video summaries, text responses, and language scenarios for logical soundness, factual accuracy, and alignment with strict prompt constraints.
• Delivered high-volume, precision-focused annotations on complex digital media datasets under tight turnaround times, adapting quickly to daily taxonomy updates.
• Documented edge-case errors, captured reproducible failure modes, and provided structured algorithmic feedback to improve prompt engineering metrics.
• Coordinated seamlessly across global, asynchronous teams using remote collaboration tools like Slack and Trello to ensure consistent data payload delivery.

ICT Attache at National Cereals and Produce Board

• Handled routine technical support, identified hardware/software conflicts, and maintained continuous operational uptime for internal staff.
• Assisted cross-functional teams in rolling out tech implementations, optimizing project coordination and workflow delivery.
