Top SchoolJavier Fernández is a systems-focused software engineer with 11 years of experience specializing in C and C++ for low-level and systems programming. He blends deep knowledge of compilers, micro-optimizations and mainstream assembly with practical experience on ARM and AVR platforms using bare-metal and RTOS (FreeRTOS, ChibiOS) approaches. Currently at ProxySQL, he applies systems-level C++ expertise to performance-sensitive code, building on prior work in reactive and declarative systems using C#, Node.js and C++. Equally comfortable with OOP and SOLID principles, he has spent recent years strengthening his functional programming skills and thinking across paradigms. He is also drawn to distributed and safety-critical systems, with early projects involving firmware reverse engineering and fault-tolerant UAV camera integrations.
