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
- After the Task Moves to the Cloud: Engineering Open Nua Cloud Agent Runtime
Who owns execution, recovery, and authority after an Agent task moves to the cloud? Engineering Open Nua Cloud Agent Runtime around durable admission, pinned snapshots, leases, uncertain outcomes, and clear application boundaries.
- Away from the Computer, Still in the Same Task: Engineering Open Nua Remote Control
Continuing the same Agent task from a phone: how Open Nua Remote Control handles connectivity, layered authorization, shared session state, mobile interaction, and recovery.
- Permission Is Not Unlimited Access: Open Nua's Mental Model for Agent Security
Why an authorized Agent still should not receive unrestricted host files, credentials, or networking: how Open Nua combines trusted decisions, constrained execution, brokered external authority, and minimal evidence into a verifiable security chain.
- Do Not Bind Tasks to Windows: How Open Nua Rebuilt Its Desktop Agent Session Architecture
Why Agent execution should survive closed windows, changing clients, and network interruptions: how Open Nua rebuilt desktop sessions around a Session Host, replayable state, and protocol conformance.
- From Scripts to Sites: Making Agent Deliverables Actually Runnable in Open Nua
From locking Plugin script dependencies with aube and uv to previewing, approving, and safely deploying static sites: how Open Nua closes the last mile of Agent delivery.
- 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.
