About me
I build AI systems where agents, dialogue, and social context converge.
My work spans LLM fine-tuning, OpenAI API integration, prompt design, domain-specific AI, evaluation systems, and early-stage prototypes. Along the way, I have explored character-based dialogue, emotion-aware voice agents with Live2D embodiment, knowledge-graph QA, and LLM-based human behavior emulation.
At the heart of this work is one practical question:
How can AI interact with people more deeply and naturally, while reasoning with a finer sense of social context?
