My technical toolkit includes platforms like OpenAI (ChatGPT), Anthropic (Claude), Google (Gemini), and various data annotation interfaces, along with strong skills in linguistic analysis and technical writing. I am adept at collaborating with teams to refine project guidelines and have contributed to automating reporting workflows, ensuring consistent data quality and efficient project delivery.
