Hi, I’m Stephen (Essell)👋 I design embedded IoT devices and gateways across both hardware and firmware — from system architecture, schematics, and PCB design through MCU integration, bring-up, debugging, and power optimization. My strongest work is where electronics and firmware need to line up properly: low-power sensors, LTE/BLE/LoRaWAN devices, ESP32-based systems, gateways, and custom embedded boards intended for real deployment rather than one-off demos. I bring 28 years of communications and integration experience into modern embedded products. I’m most useful on projects where the hard part is getting power, wireless behavior, firmware, and real-world constraints to line up properly — not just producing code or a PCB in isolation. I work with proper bench equipment for bring-up and validation, so debugging is based on measurements rather than guesswork. Typical work includes: • IoT sensors and gateways • PCB design and hardware bring-up • MCU firmware in C/C++ • LTE, BLE, Wi-Fi, LoRaWAN, MQTT • Low-power and battery-operated devices • Debugging, refinement, and rescue of troubled prototypes If you need someone who can take responsibility across the embedded side of the product, I’d be glad to discuss the project 🚀
