ABOUT ALBERT CHRISTOPHER HALIM
The University of British Columbia shaped my expertise in data science, equipping me with skills in natural language processing and advanced machine learning. During my capstone project at Quant Valuations, I developed a robust financial forecasting model by integrating textual and financial data, leveraging LLM-based text analysis to achieve a 5.7% error rate. At Bank Central Asia, I contributed to modernizing operations by migrating databases to PostgreSQL and designing APIs with Java Spring Boot. My work enhanced data accessibility and streamlined applications. Passionate about enabling data-driven decisions, I aim to bridge the gap between cutting-edge technology and impactful business solutions.Specialties: Machine Learning, Natural Language Processing, Data Engineering, Data Visualization, Statistical Modeling, Java, Python, SQL, Mainframe, PostgreSQL, Spring Boot.
