At Lingkar9, I build full-stack products, including a hospital information system on Go microservices for registration, encounters, billing hooks, and clinical records. I focused on reliable APIs, role-based access, and audit-ready patient data flow.
I also digitized plant-wide HSE permits with auto-generated PDFs and a QR LOTO logbook, and built an e-clinic covering patient flow, EMR, wellness forms, and medical supplies. Earlier, during my internship at PT Mitrasoft Global, I shipped an invoice tracker that made admin work faster and easier to audit.
