(Hello, World!)

👨‍💻 Hi, I'm Jiayu — an Engineering Enthusiast 🚀

Curious learner · Engineer at heart · Always building and learning

Homepage GitHub

👋 About Me

  • 🔧 I am interested in embedded systems, FPGA, and digital communications.
  • 📡 I enjoy exploring signal processing, control systems, and practical software tools.
  • 💻 I like working across both hardware and software to turn ideas into working results.
  • 🌱 I keep learning through hands-on practice, experimentation, and careful documentation.
  • 🧠 I value engineering work that is clear, reliable, and reproducible.
  • 📍 Based in Hong Kong.

🧰 Technologies & Tools

C C++ Python MATLAB Verilog and FPGA STM32 FreeRTOS
Arduino Raspberry Pi Linux Git Docker MySQL Visual Studio Code

🌱 How I Work

  • Learn by building — knowledge becomes useful when it is applied.
  • Keep things understandable — clear structure and documentation matter.
  • Aim for reliability — good engineering should be testable and reproducible.
  • Stay curious — every problem is a chance to learn something new.

💬 A Little More About Me

I enjoy the process of taking an idea, understanding the problem behind it, and improving the result step by step. For me, engineering is not only about making something work—it is also about knowing why it works and making it easier for others to understand.

Stay curious. Keep building. Make every idea a little more real.
