Freelancer Overview

I have experience in AI data annotation across two Scale AI platforms. At Remotask (2021–2022), I annotated images and videos for autonomous driving datasets, labelling traffic lights, licence plates, pedestrians, and vehicle colours. At Atlas (January 2025–present), I perform ego-view video annotation; watching first-person footage and writing step-by-step descriptions of human activities such as washing dishes, folding clothes, and cleaning, to train AI activity recognition models. Across both roles, I have consistently maintained a 98–100% accuracy rate. I am experienced in following detailed annotation guidelines, working within proprietary annotation tools, and delivering high-quality output across large volumes of tasks.

At Atlas, I work on ego-view video annotation to train AI activity recognition models

At Atlas, I work on ego-view video annotation to train AI activity recognition models. I watch first-person footage recorded from the perspective of the person using the device, and produce detailed step-by-step descriptions of every action they perform — for example, picking up a plate, rinsing it under water, placing it on a rack to dry. The goal is to give the AI an accurate, granular understanding of everyday human activities like washing dishes, folding clothes, arranging items, and cleaning. I work within Atlas's internal annotation platform, following structured guidelines to ensure consistency and accuracy. I have maintained a 98–100% accuracy rate throughout my time on the platform.
