My work spans text-to-image evaluations, video and audio annotation, and AI response labeling for leading platforms including Handshake AI, Labelbox, and Mercor. I have expertise in analyzing prompts, comparing model outputs, and ensuring high-quality labeled datasets through meticulous QA and error correction. My technical toolkit includes Charles Proxy, Jira, Airtable, Salesforce, TestRail, and advanced AI tools such as ChatGPT, Midjourney, and Deepseek.
