Translating conceptual CAD design bytes into high-performance physical atoms through precision hardware engineering, custom PCB design, and renewable energy prototyping.

I am a passionate Mechatronics Engineer and R&D Product Development Intern focused on the design, prototyping, and validation of complex electro-mechanical systems. My engineering approach centers around "CAD-to-Reality"—bringing 3D models to life as robust physical assets via simulation, material analysis, and hardware-software orchestration.

With expertise spanning embedded firmware (C/C++), hardware-software communication, custom PCB routing, structural CAD design, and empirical validation under real-world constraints, I build systems engineered for maximum reliability and efficiency.
