Helping enterprises move from digital foundations to AI‑native operations.
I am Yujie Zhou. I focus on more than adding AI to existing workflows. I design the platforms, knowledge systems, collaboration models, and governance that make Agents part of an enterprise's evolving infrastructure.
Selected project
Open Nua
An Open Nua project case on bringing conversations, workspaces, knowledge, Plugins, authorization, and governed execution into one enterprise Agent workbench.
Writing from the work
- A Knowledge Base Is Not a Search Box: Building Personal Wiki and Code Wiki in Open Nua
A personal knowledge base is more than a search box: how Open Nua uses one source, revision, and evidence foundation to build distinct Personal Wiki and Code Wiki experiences.
- Beyond “Summarize the Chat”: How Open Nua Compacts Long-Running Agent Context
Context compaction is more than summarization: how Open Nua separates conversation facts from model projections while preserving tool, recovery, and provider boundaries.
- Starting by deleting Memory: how Open Nua rebuilt long-term memory
From removing a heavyweight Memory implementation to rebuilding local long-term memory with an append-only log, rebuildable tree, current facts, and bounded context.
- The Black Screen Wasn't CSS: How Open Nua Stopped a Snapshot Storm in the Conversation Detail View
How repeated Vibe Trading black screens led Open Nua to diagnose cross-process full-snapshot amplification and close the loop with revision deduplication, frame coalescing, and crash recovery.
- From a Tool Call to Recoverable Execution: How Open Nua Governs Agents
How Open Nua governs autonomous Agent execution with identity, Capabilities, scoped credentials, HITL, recovery semantics, and minimally sufficient evidence.
- More Than Tools: How Open Nua Turns Plugins into Domain Products
How Open Nua composes Skills, Capabilities, Apps, state, and governed runtimes into installable, auditable domain products.
- Fix the ruler before ranking the models: turning a Code Wiki failure into an Agent benchmark
How a failed Code Wiki revision became a reproducible, auditable Agent benchmark that separates model and system failures.
