Secure IoT Device Development

I need an expert to develop a secure IoT device using the Nordic nRF91 platform. The device should integrate LwM2M (Anjay SDK) for device management, firmware updates, and remote monitoring, with OSCORE for securing data transmission, command/control messages, and authentication processes.

Key Requirements:
- Implement LwM2M functionalities:
- Device Management
- Firmware Updates
- Remote Monitoring
- Integrate OSCORE for:
- Securing Data Transmission
- Securing Command/Control Messages
- Securing Authentication Processes

Ideal Skills and Experience:
- Proficiency in Nordic nRF91development
- Strong knowledge of LwM2M and OSCORE
- Experience in implementing secure IoT solutions
- Familiarity with device management and firmware update protocols
