About

Hardware engineering with a practical lab mindset.

I am an electronics hardware engineer specializing in PCB design, embedded control, and validation for real-world systems.

My work bridges circuit design, lab testing, and system integration. I enjoy translating technical requirements into reliable electronics—from component selection and schematic design to PCB review, board bring-up, and measurement-led debugging.

I am particularly interested in robotics, automotive applications, and embedded systems, where electronics must be robust, measurable, and practical. My goal is to develop hardware that is not only functional on paper, but validated, well understood, and ready for integration into a complete system.
