Turning data into impact

I'm a Statistics & Data Science student at Universitas Negeri Semarang (UNNES) with a strong passion for turning complex data into actionable insights. My work spans natural language processing, predictive modeling, and data-driven public policy -- from forecasting electricity loads to analyzing public sentiment around national government transitions.

Beyond research, I actively lead organizations, speak at bootcamps, and compete in national data science competitions. I believe data has the power to solve real social problems -- and I'm here to build those solutions.
