Bridging data
and decisions
As a highly motivated Informatics Engineering fresh graduate from the University of Muhammadiyah Prof. DR. Hamka, I've developed strong capabilities in data analytics, machine learning, and data visualization through academic research and organizational experience.
I combine technical rigor—developing high-accuracy exchange rate forecasting models—with business acumen in churn reduction and stakeholder reporting. I'm adept at bridging the gap between raw data and executive decision-making through structured reporting and collaborative project management.
