What I'm looking for
I've built SISWOOD IoT devices shipped to 30+ countries, owning firmware, PCB and enclosure design, manufacturing, Flutter integration, and Go/Redis/PostgreSQL backend systems.
I'm now deepening my embedded work with ESP32, ESP-IDF, FreeRTOS, BLE, MQTT, OTA, Zephyr RTOS, Matter, and Nordic nRF54. I built a custom Zephyr driver for a Sensirion environmental sensor and a live Matter-over-Wi-Fi demo, while progressing CCNA studies for hands-on network and data-centre roles in Ireland.
