I built a 9-module Medical Care web application for PT GS Battery, covering MCU management, employee claims, billing, reporting, and dashboards. I integrated OCR and Gemini AI for document data entry and designed SQL Server tables and views supporting more than 20,000 records.
At PT Sato Label Solutions, I developed REST APIs and an Android app for an RFID-based inventory system, including Stock In, Stock Out, Stock Taking, and Picking List modules. I implemented offline-first synchronization with Room DB and WorkManager for field operators using RFID handheld readers.
I'm building the Topaz RW Information System to manage neighborhood resident data, with role-based access and encryption for sensitive information. Across my projects, I've also developed REST APIs with JWT authentication and worked with clients and stakeholders to clarify requirements and deliver updates.
