About

Building the future of AI through research and engineering

I am a Software Engineer at AWS GuardDuty with a deep passion for advancing Artificial Intelligence, particularly in Natural Language Processing (NLP). My work focuses on addressing the limitations of current AI systems in areas such as robustness, generalization, and ethical impact.

Through projects involving benchmark development, data quality improvement, and efficient training strategies, I aim to create AI models that are not only technically advanced but also socially responsible. I bring over six years of industry experience and three years of research to my work, where I explore cutting-edge solutions in machine learning, threat detection, and adaptive problem-solving.

My research interests include multi-agent systems, AI safety, and human-AI collaboration. I believe that by combining human "slow thinking" with AI's "fast thinking," we can achieve extraordinary outcomes while maintaining ethical considerations and positive impacts on human psychology.
