About | YANG's Blog
To record is to think more clearly. To publish is to truly own what you know.
I’m YANG, Head of R&D for an education SaaS product. I focus on complex business systems, engineering collaboration, AI Coding, and personal knowledge systems.
My writing is not centered on tool tutorials. It is about how AI enters real workflows, how it changes engineering systems, and how individuals can turn experience into reusable assets.
What I Think About
- The architecture and construction of complex business systems
- How AI enters real workflows, real tasks, and real collaboration
- How individuals can turn experience, judgment, and workflows into reusable long-term assets
What I Can Help You Understand or Solve
- How to move AI Coding from “writing code faster” into team-level engineering practice
- How to organize requirements, iterations, reviews, production issues, and delivery routines into a more stable engineering system
- How to handle architecture evolution, platform capabilities, and collaboration boundaries in complex education SaaS products
- How to use writing, knowledge management, and content systems to turn scattered experience into compounding assets
What I Am Working On
- Clarifying system boundaries, platform capabilities, and evolution paths around a long-running education SaaS system
- Bringing agents and tools such as Claude Code, Cursor, Codex, and Harness into real engineering workflows
- Building my own knowledge and content system with Obsidian, Notion, NotebookLM, and this blog
Tools I Use
- AI: ChatGPT, Codex, Claude Code, Youmind, Cursor, NotebookLM
- Writing / PKM: Obsidian, Notion
Working Beliefs
- Architecture is not about drawing many boxes. It is about defining boundaries, contracts, and paths for evolution.
- The key to AI Coding is not code generation. It is putting engineering rules, architectural boundaries, and verification standards into context.
- Writing is not the desire to express. It is compressed thinking. If I can write it clearly, I probably understand it better.
