I am a freelance data annotator with 5+ years of hands-on experience delivering labeled data for AI projects across healthcare, e-commerce, facial recognition and autonomous vehicles, working with global clients and strict production standards.

I have completed 200+ hours of task-based annotation and QA projects and consistently achieved 98%+ accuracy in production and QA stages while collaborating on large annotation batches with tight guidelines. I routinely use tools such as Labelbox, CVAT and SuperAnnotate and contribute to platform-scale efforts on Appen, Scale AI, Remotasks, Clickworker and TaskUs AI.

I also bring SEO training and prompt-writing experience for generative AI, plus social media evaluation and content rating background. I thrive in remote, deadline-driven environments and prioritize clear communication, efficiency and high-quality output.
