Hossam As

Mechatronics Engineer with 5+ years of engineering experience, including 4 years in embedded software development and 1 year in industrial automation. My background combines firmware development with hands-on work in PLC, SCADA, HMI, and industrial control systems. I work mainly with C/C++, ARM Cortex-M, FreeRTOS, BLE, PSoC 63, sensors, and low-level interfaces, and I have also built and recovered PLC/SCADA systems using Siemens and INVT platforms.

I am comfortable debugging problems, integrating hardware and software, and taking an engineering task from development through a working result.

Embedded Software Engineer at PAIR Holdings, Inc. (2023-08 – 2026-09)

• Lead firmware development for smart wearable products, including the Smart Earring SEIS system for vital-sign telemetry, continuous heart-rate monitoring, fall detection, and automated emergency calls.
• Write, optimize, and debug embedded C/C++ software for microcontroller-based systems using Bluetooth Low Energy (BLE) for reliable, low-power communication.
• Integrate and troubleshoot sensor interfaces and battery-management hardware for motion detection, fall detection, and power-management features.
• Develop and tune digital signal-filtering techniques to improve sensor-data quality, reduce noise, and provide more reliable signals for downstream processing.
• Work with battery-management and low-power power-management solutions to optimize operating modes, reduce power consumption, and extend battery life while maintaining required system performance.
• Optimize memory usage and linker scripts by mapping custom memory regions to make better use of the available system resources.
• Plan development tasks, estimate effort, investigate issues, and deliver firmware features within project deadlines.

Freelance Embedded Software Developer (2023-05 – 2023-08)

• Built embedded solutions for independent engineering projects using AVR and ARM Cortex-based platforms.
• Followed MISRA-oriented coding practices to keep the code maintainable, reliable, and suitable for safety-conscious embedded development.

Maintenance Engineer at Egyptian Air Defense Forces (2021-06 – 2022-06)

• Handled maintenance and fault diagnosis for a solar power station, covering the solar panels and related control-system equipment.
• Supervised inspections, troubleshooting, repair, and restoration work to keep the station operating reliably.
