Back to original languageAbout Ahmad
I am an Embedded Firmware / Software Engineer with a strong focus on embedded C/C++, FreeRTOS, and IoT systems. I help companies develop, improve, and integrate reliable embedded software for prototypes and production-oriented solutions.
My experience lies mainly in working with ESP32 and STM32 platforms, real-time applications, and communication via MQTT (including TLS and certificates). I have worked on IoT gateways and safety-related systems where stability, clear architecture, and maintainability are central.
Clients engage me for:
Firmware development and refactoring (C/C++)
FreeRTOS-based real-time applications
IoT connectivity (MQTT, cellular modems, AT commands)
Hardware-software integration and debugging
Proof-of-Concepts and prototypes
I work in a structured manner, contribute to architectural decisions, and ensure clear documentation. My strength lies in quickly understanding existing systems and delivering practical, working solutions — without unnecessary complexity.
Are you looking for an embedded engineer who can independently contribute to IoT and firmware projects? Then I would love to connect.
