Embedded Firmware Developer

• Designed hardware and developed firmware for the vehicle data network (CANBUS) logger optimized for mining dump trucks: captures all messages, intelligently reduces size (through thresholds and timing), and transmits selectively (via WiFi/3G). Enables proactive maintenance by pinpointing root causes and significantly slashing costs.
• Secured OPC Data Collector, extracted critical process data using advanced filters, optimized real-time updates in MariaDB. Dual-layer encryption (PGP Over IPSEC) ensured secure AI server transmission and data compliance. (OpenWrt, C, Python, MariaDB)
