禾麦科技开发(深圳)有限公司 Tech Stack

IoT integration platform for industrial device management and energy systems

Software Development 深圳市, 广东省 ~5 employees

Roymark is a 5-person team building IoT connectivity and private cloud systems, primarily for electricity and energy infrastructure. The stack reveals deep embedded systems expertise: MQTT, Modbus, CAN, BACnet, and KNX protocols sit alongside Java/Spring Boot backends, Redis caching, and MySQL persistence—a pattern typical of companies bridging legacy industrial hardware to modern cloud architectures. Pain points around device integration complexity and system scalability suggest they're addressing real operational friction in connecting heterogeneous equipment.
