// about
I am an explorer driven by a passion for analog IC design, low-level system architecture, and the emerging field of integrated photonics. I enjoy solving complex problems and bridging the gap between traditional electronic engineering and modern optical sciences.
My hands-on experience spans PCB design, firmware development, and register-level programming across STM32, ARM Cortex, and ESP32 platforms. I am deeply curious about how power-efficient electronics and real-time control systems can be leveraged to optimize Photonic Integrated Circuits (PICs) and optoelectronic applications.
I am eager to collaborate with like-minded innovators in world-class research environments to bring advanced technologies to life — and I love mentoring young minds to spark their curiosity for innovation.
