About
I am Tecker Yu, an AI Native cloud engineer. I write about AI software engineering, cloud infrastructure, backend systems, long-term investing, and the way technical people can think more clearly.
This site is FloatShell, a public notebook for my work and thinking. Some posts are engineering case notes, some are essays about AI, business, investing, and life. I care less about publishing around every trend and more about reusable mental models, real implementation details, and ideas that can be reviewed later.
What I Write About
- AI Native software engineering: prompts, context engineering, agent workflows, tooling, and evaluation.
- Backend and infrastructure: Go, Linux, networking, databases, distributed systems, and performance.
- Investing and business: technology cycles, company fundamentals, productivity tools, and long-termism.
- Writing and thinking: turning fuzzy experience into clear, testable notes.
