## About Me

I am a data-focused computational linguist with experience in natural language processing (NLP), AI data annotation, and speech technologies. I am adept in phonetics, prosody, and linguistic data curation. Currently, I am completing intensive data science training with hands-on exposure to Python, SQL, and NLP tools. I am skilled in model evaluation, multilingual annotation, and cross-functional collaboration. I am committed to bridging language science and artificial intelligence with scalable, real-world solutions. My passion lies in AI, NLP, and the intersection of linguistics with AI, and I am drawn to multicultural, multilingual settings with a deep appreciation for cross-cultural collaboration.
