DevHeads is a knowledge-sharing community and publishing platform for engineers working on embedded, IoT and systems-level technology. Responsible for: • Creating technical content based on hands-on, real-world experience, sharing practical insights and lessons learned while exploring and mastering our technologies, with the goal of building recognized expertise over time. • Producing Yocto and embedded-systems–focused blog content, with emphasis on BSP layers, ARM-based architectures, and low-level system integration. • Leading and maintaining the GitHub platform, ensuring it remains well-structured, scalable, and aligned with modern CI/CD practices and evolving tooling. • Providing continuous technical support and guidance on the DevHeads Discord server.

Contribute to the enhancement of embedded firmware for electricity smart meters by improving software design to increase maintainability, boost performance, and enhance portability. Tasks: • Analyzed customer requirements (SDD) related to smart meter functionalities, including billing, communication, energy management, and fraud detection. • Designed and developed BSPs and drivers for displays, memory modules, and sensors on smart meter boards, improving system performance and maintainability. • Designed and integrated new services and features in compliance with DLMS/COSEM standards and HDLC-based communication. • Implemented LTE Cat-M1 and NB-IoT protocols to connect smart meters to Sagemcom’s SECONIA IoT platform, ensuring reliable and secure data transmission. • Designed and integrated middleware for a multi-MCU/MPU smart meter, enabling secure inter-chip data transfer, serialization, and storage in external memory. • Built embedded Linux images and services for smart meters using Yocto, with a focus on kernel optimization, secure and trusted boot, and Docker-based applications. • Conducted technical code reviews to ensure quality and compliance in driver development across multiple components. • Performed integration, regression, and requirement testing to validate final product functionality. • Acted as a trainer for integrating STMicroelectronics H5 low-level drivers and TrustZone features. • Used CI/CD tools such as Jenkins and GitLab to support build and integration workflows.

MDG represents around 3 000 employees (mainly R&D teams in France) located in 40 countries. It is addressing 2 major activities: first, General Purpose (GP) Microcontrollers, Memories and Secure Micro (MMS Subgroup) covers all products based on Non-Volatile Memory technologies. It represents 80% of MDG business and second, The RFC Sub-Group focusing on Radio Frequency, Digital & Mixed Signals activities, represents 20% of MDG business. Responsibilities: • Continuous enhancement of HAL/LL validation environments (support missing IP’s, ACI jobs follow-up, reporting…) • Lead and participate to the activities of HAL validation environments automation: SW&HW setup, ACI configuration and follow-up, internship supervision… • Work in collaboration w/ Maintenance and GitHub teams to ensure high quality of deliverables. • Help to fix reported bugs in line with defined maintenance strategy for STM32Cube firmware packages

Currently, I am an embedded software engineer at Heptatronics company (Software Unit ), I am included in: " Smart wearables Project " and " Infinity IoT " Project. Charged for: • Internal consulting ( Bill of materials, Statement of work analysis, Market analysis .etc ). • From scratch firmware development for smart wearable devices • Debugging and testing • Real-time OS to adapt with user experience • Data and Hardware Security • Wireless and low-power technologies specialist • Permanent improvement of quality

I was in charge of developing modular connected technologies that will be installed inside buildings. The goal is to make buildings more secure, automated, and comfortable. Responsibilities: • Clients need analyzing (Light Automation, Smart garden, Cameras, etc.) • Hardware and Software Design ( Diverse platforms ) • Hard tests and quality control • Field implementation ( Houses, shops, administrative institutions, etc. ) Tags: C/C++, Python, BLE, WIFI, low power, Arduino, ESP32, Raspberry Pi, Android Studio, Easy EDA
