HAMAS SAEED

Embedded Firmware & IoT Engineer

Low-level MCU • RTOS • Secure Cloud Connectivity

Embedded firmware & IoT engineer specializing in low-level MCU firmware (C/C++), RTOS-based systems, and production-grade IoT cloud integration.

Experienced with STM32, nRF52, ESP32, implementing BLE, Wi-Fi, MQTT, HTTP, OTA, and secure device provisioning. I design robust firmware architectures, write custom drivers and middleware, and connect devices reliably to AWS IoT, custom backends, and dashboards—from hardware bring-up to scalable cloud-connected products.
