👋Hi, I'm sangui（三桂）
Java developer · Graduate student · Builder of systems and habits
“Code is structured thought made visible.”
I'm a graduate student in Computer Science, currently focusing on Java backend & full-stack development.
I care deeply about clarity, structure, and boundaries — in systems, in code, and in thinking.
I tend to believe that:
- good software is designed, not assembled
- complexity should be earned, not assumed
- and most problems become smaller once they are described precisely
I enjoy building things slowly, understanding them from the inside out.
Outside of code, I train regularly.
Not for competition, but for discipline, feedback, and long-term consistency.
- Becoming someone who can design and reason about entire systems, not just write features
- Building software that is maintainable, understandable, and honest
- Keeping a personal technical archive — notes, projects, and reflections — that compounds over time
I’m less interested in trends, and more interested in foundations.
A personal blog where I write about:
- programming and system design
- learning processes and mistakes
- methods, habits, and long-term thinking
No algorithms for traffic.
Just notes meant to be revisited.
“Write to understand. Keep what survives.”
- I prefer clean file structures and consistent formatting
- I believe logic is not opposed to creativity — it protects it
- Nostalgic music sometimes says more than documentation
- Simplicity is often the result of restraint, not lack of effort
“The limits of my language mean the limits of my world.”
