Connected Product Embedded & IoT Engineer

Nick Brook is a Connected Product / Embedded & IoT Engineer operating through his consultancy, NRB Tech. He specializes in helping startups and small teams ship reliable connected products, offering end-to-end design, build, hardening, and support for production-ready IoT and embedded systems. This includes firmware, wireless connectivity, secure OTA updates, and companion iOS/Android applications. His recent work includes developing a Zephyr/nRF firmware platform, iOS/macOS/Android apps, and a developer SDK for Bluetooth pedals (AirTurn); USB-MIDI guitar-pedal controllers with reliable OTA (Positive Grid); an LTE-M vehicle security platform with BLE coexistence and aggressive low-power management, coupled with an AWS backend (KēZ); and a remote-managed Raspberry Pi fleet for an outdoor interactive light installation (ROUTES). He is particularly skilled in BLE/Nordic/Zephyr firmware, cellular IoT with low-power constraints, secure boot + OTA, hardware-paired iOS apps, technical audits of existing products, and long-term device maintenance. With an MEng in Electronic Engineering and a CSSLP certification, he possesses strong hardware debugging capabilities, though he does not undertake PCB layout or RF design. He prefers an outcome-based approach, typically starting with an audit or discovery phase to ensure clarity before commencing larger projects.
