Message

At Forage, I completed Tata Group’s GenAI-powered data analytics simulation for Tata iQ’s Financial Services team. I used GenAI tools for exploratory data analysis, assessing data quality and identifying risk indicators to inform predictive modeling.

I proposed a no-code framework for assessing customer delinquency risk and designed an AI-driven collections strategy. My work incorporated ethical AI principles, regulatory compliance, and scalable implementation frameworks.

At Pojok Statistik UNDIP, I served as Head of Group 2 in the Media and Branding Division, overseeing a monthly data storytelling design program. I also provided statistical consulting, including clustering analysis of a village-level cardiac disease risk survey; as a Data Science Intern at Badan Pusat Statistik Kota Semarang, I assisted with data analysis and entry and supported the Desa Cantik survey program.
