Hello! I am Steven Immanuel C. Girsang (also known as Steven Girsang / StevChrist), a fresh graduate in Data Science from Telkom University, Bandung.
I am deeply passionate about how data can uncover hidden patterns, power machine learning models, and solve real-world industry challenges. During my academic journey and organization roles, I developed strong capabilities in ML algorithms, Data Warehousing, Business Intelligence dashboards, and full-stack web applications.
♾️INTERESTS & FUN FACT
Outside tech, I enjoy gaming, listening to music, watching movies, photography, and video editing.
💡Fun fact: I can sleep over 13 hours & love deep focus music playlists!
