Data Science with less than a year in Data Analysis & Machine Learning.
Bachelor's Degree in Data Science Technology from Airlangga University, with demonstrated adaptability and hands-on experience through academic projects, collaborative teamwork environments, and internships in both the banking and public sectors. At Bank Rakyat Indonesia (BRI), I supported workforce distribution optimization initiatives through workforce capacity analysis, staffing allocation assessment, and operational support to improve organizational effectiveness and decision-making. Previously, at BMKG Maritim Tanjung Perak Surabaya, I was involved in the end-to-end management of meteorological data, including data collection, validation, analysis, and reporting to produce climate and rainfall insights. Skilled in data analysis, reporting, data mining, machine learning, and data-driven problem solving, with proficiency in Python, R, MySQL, and Microsoft Excel. Possessing strong teamwork, communication, resilience, and analytical thinking skills, I am ready to apply my data and technology expertise in a professional environment.
