Ai Engineer

 I’m a Master’s student in Artificial Intelligence graduating in June 2025, with hands-on experience developing LLM-based systems, prompt engineering tools, and AI agents. My work bridges research and application—I've published an SCI paper on long-term memory frameworks for AI NPCs and built a portfolio of practical AI tools for eCommerce, dialogue systems, and intelligent automation.

Looking for: Full-time or internship roles in AI R&D, LLM applications, or AI engineer positions (remote or onsite in Singapore / U.S.). Open to startups or large enterprises where I can contribute to cutting-edge LLM systems, AI agents, or multimodal applications.
