About Me
Data Meets Real-World Systems
I am a final-year Statistics undergraduate at Institut Teknologi Sepuluh Nopember (ITS) with a strong focus on data analytics in operational and logistics environments.
Through hands-on experience in transportation and supply chain systems, I have developed the ability to transform raw operational data into structured insights that improve efficiency, accuracy, and decision-making.
I am particularly interested in building data-driven systems that do not just analyze performance, but actively contribute to process improvement and organizational impact.
