ImageBounding Box
Worked on bounding box annotation tasks to support the training of object detection models by accurately identifying and labeling objects within images. My responsibilities included drawing precise bounding boxes, assigning correct class labels, and reviewing annotations for consistency and accuracy across large data sets. I followed strict guidelines and quality checks to reduce errors such as misalignment or mislabeling while maintaining efficiency.

VideoEvaluation Rating
My contribution to video evaluation projects focused on training computer vision models by analyzing and annotating video data. The project involved identifying objects, actions, and patterns within video clips and ensuring that annotations were accurate, consistent, and aligned with task guidelines. I performed tasks such as labelling frames, reviewing annotations for quality, and validating outputs against defined standards. This role required strong attention to detail, pattern recognition, and the ability to make consistent, high-quality judgments in a fast-paced environment.

TextPrompt Response Writing SFT
I worked on AI training and evaluation projects focused on prompt writing and response assessment, contributing to workflows similar to reinforcement learning from human feedback (RHLF). The scope of the project involved improving the quality, accuracy, and reasoning ability of AI-generated responses across a variety of domains. My responsibilities included analyzing responses for clarity, factuality, helpfulness, naturalness, and instruction adherence. Provided detailed justifications for my evaluations and flagged errors. I worked on high-volume task batches, and I strictly followed annotation guidelines, applied review checklists, and maintained high accuracy standards throughout.
