Design and implementation of software components in C++. Analysis, correction, and refactoring of existing codebases to improve maintainability, readability, and reliability. Definition of software architecture (API, layer separation, modularity). Development and integration of reusable software libraries.

Design and development of C/C++ libraries, applying advanced OOP principles and modern language features for modular, high-performance, and scalable embedded solutions. Robust implementation of MQTT communication in C++ via Paho MQTT, integrated into embedded systems to ensure reliable exchange in distributed environments. Development of a high-performance data bus for communication between software components (libraries/daemons). Creation of a Rust service dedicated to MQTT communication management, leveraging the language's advantages in memory safety and performance. Integration of network protocols (TCP/IP) to facilitate inter-component communication within the embedded system. Analysis and resolution of complex C/C++ bugs to ensure the stability and performance of critical systems. Design and development of Qt applications (C++), with fine-grained signal/slot and network module management for real-time and supervision systems. Seamless integration of the MQTT layer within Qt applications for telemetry data visualization or processing. Use of QML/Widgets to create user-friendly and responsive interfaces, adapted to embedded system constraints. Setup and maintenance of a multi-platform build ecosystem based on Conan and CMake for internal dependency management. Development of Python and shell scripts to automate build, test, packaging, and deployment tasks. Writing and execution of automated tests with Robot Framework, using custom libraries (Python)

Development of a CAN data visualization solution. This is a software application developed with Qt(C++) that communicates with an STM32 board via serial communication (UART). The STM32 board receives data from the CAN bus and sends it to the Qt application; the software application can also send data to the CAN bus. C, C++, Qt, STM32 board, FreeRTOS, CAN 2.0A/B, FDCAN, UART
