Freelancer Overview

I am an experienced AI data annotator and training specialist with hands-on expertise in text, audio, image, and video labeling across diverse domains. My background includes contributing to large-scale projects such as warehouse safety video annotation, event segmentation, and action labeling for industrial environments. I also have experience in natural language processing (NLP) tasks, including prompt/response evaluation, dialogue annotation, and reinforcement learning with human feedback (RLHF) for large language models. In addition to annotation, I bring a strong technical foundation from my DevOps and cloud engineering background, which enables me to quickly learn new labeling tools, follow complex guidelines, and maintain accuracy under tight deadlines. My attention to detail, ability to break down multi-step events, and experience with structured data workflows make me well-suited for projects requiring precision and consistency. I am excited to contribute my skills to training AI systems that power safer automation, more accurate computer vision models, and smarter language technologies.

Warehouse Safety Video Captioning – Forklift & Worker Annotations

PlaymentVideoSegmentation
Worked on annotating warehouse safety videos. Tasks included writing dense captions for individual worker and forklift actions, generating global captions to summarize overall activity, and ensuring adherence to strict guidelines on banned words, single-action focus, and actor-based splitting. Maintained high accuracy while managing large volumes of data for AI model training and validation.
