PROFILE
Petro Karashchenko
Over three months, contributed to apache/nuttx and apache/nuttx-apps by delivering production-grade features and targeted fixes. Developed secure MQTT messaging with MBED TLS integration, enabling configurable TLS encryption and certificate verification in C for IoT deployments. Improved build reliability and cross-platform support by refactoring Makefile logic to ensure nanopb unpacking works seamlessly on macOS and other environments. Enhanced the MCUboot bootloader by optimizing configuration for reduced code size and risk, while extending the C++ standard library with numerical precision and alignment features. Demonstrated expertise in C, C++, build systems, configuration management, and embedded systems through focused, maintainable engineering solutions.
