Hello there! I'm Dean Hans!

I am an AI Engineer at Egeroo.AI (KPSG Group / Anabatic Technologies), where I build Generative AI ecosystems that power intelligent chatbots and advanced automation use cases. Concurrently, I am a final-year Computer Science student at Bina Nusantara University, specializing in Intelligent Systems.

My core focus lies in AI, machine learning, deep learning, and data science. I am deeply passionate about leveraging AI to solve complex, real-world problems through data analysis, predictive modeling, and workflow automation. I recently demonstrated this commitment by publishing academic research in the field and developing independent projects to address my own real-world challenges.

I am always open to discussing tech, data, and innovative AI solutions. Feel free to reach out to me directly, or say hello to my chatbot, Dio!
