Second-year Informatics student at Institut Teknologi Bandung (GPA 3.90/4.00) focused on security and web engineering. I want to become an ethical technologist who builds systems that work, stay secure and can be trusted, while I keep learning and give back to the communities I work with. I bring care and attention to detail to every project, from web apps to security tools. My strength is adapting across technical domains; my growth area is depth, which I work on by setting focused learning goals in cybersecurity.
