I am a Senior Embedded Software Engineer with 10+ years of experience developing reliable and production-grade systems across microcontrollers, microprocessors, and embedded Linux platforms. I have worked on a wide range of environments, from bare-metal and FreeRTOS-based systems to Linux kernel and user-space applications.

I have strong experience in system architecture design, building modular, scalable, and maintainable software systems. In addition to hands-on development, I have taken on technical leadership roles as a System Architect and Team Lead, guiding teams and managing complex development processes.

My expertise includes multithreaded and event-driven systems, where I apply OOP, SOLID principles, and TDD to create clean and robust codebases. I am also Linux kernel development, including device drivers and system-level optimizations.

I also focus on quality and automation, designing test infrastructures using Robot Framework and Python, integrated with CI/CD pipelines for continuous testing and reliable releases. Additionally, I have developed Qt-based simulation systems (SIL) to enable efficient development without hardware dependency. 💡 Building scalable, reliable, and fully tested embedded systems.
