I'm building enterprise mobile and web products at PT Berlian Sistem Informasi, part of Mitsubishi Group. I designed a Flutter-based Lead Management System that centralizes national sales data for thousands of active dealer users.

I develop responsive real-time systems with .NET, SignalR, Hangfire, and Redis, including automated processing, instant sales and service updates, and Firebase notifications. I also built GPS and mock-location detection for an Attendance App, ensuring 100% accuracy in attendance data.

Previously, I built telemedicine video and voice consultations at PT Hewania Solusi Digital and video-sharing, voting, automotive e-commerce, and order-tracking applications at PT Mitra Aplikasi Digital. I focus on clean architecture, efficient media handling, reliable deployments, and mobile experiences that work well in low-bandwidth environments.
