Message

At PT Pratesis, I contributed to SINNO Worklog Management by developing timesheet and employee activity tracking features. I implemented manual worklogs, timer tracking, approval workflows, reporting, and backend business validations.

As a Computer Architecture and Organization Teaching Assistant at Del Institute of Technology, I mentored Informatics and Information System students in CPU simulation, RAID concepts, and Assembly programming. I also guided students through laboratory exercises and debugging Assembly code.

On my MatchUp project, I developed an Android app for managing football and basketball matches, statistics, and goals. I used Jetpack Compose, MVVM, and Hilt, and integrated RESTful APIs with Retrofit and JWT authentication.

I also developed web and mobile projects including a village information system, a financial management platform, and an iOS grade calculator. I'm studying for a Bachelor of Informatics at Institut Teknologi Del, with a focus on Artificial Intelligence, Software Engineering, Project Management, and Game Development.
