At MINERGO SYSTEMS, I developed a large-scale IoT fleet management integration platform for 24/7 mining operations. It earned the top score among three competing vendors during the POC for PT Golden Energy Mines Tbk (Sinarmas Mining), the company's first won tender.

I improved stability for 1,000–2,000 users, raising Redis cache hit rates to 86–92% and reducing CPU usage from 73% to 19%. I also led R&D for Mineguard, an IoT wearable system that analyzes truck operators’ fitness for duty using biometric data.
