AI agents / compute infrastructure / visual systems

Xinyu (Cindy) Zhang

Building AI-native systems for the physical world of compute.

Data scientist and software engineer working across AI agents, operational intelligence, and data center workflows. I like turning messy technical systems into tools, maps, and stories people can actually use.

research visuals

Readable maps for hard systems.

New public work will live here: visual essays, product comparisons, and interactive explainers about AI agents and data center operations.

visual research

Data Center Field Atlas

A Pudding-style explainer series on compute infrastructure, factory testing, cluster operations, and the strange metrics that decide whether machines are ready for production.

coming soon

agent systems

Agent Evaluation Notes

Notes on tool use, traces, guardrails, handoffs, and the practical difference between impressive demos and dependable operational agents.

in progress

industry maps

Compute Ops Comparisons

Visual comparisons for vendors, workflows, failure modes, and reliability patterns across the data center ecosystem.

planned

selected work

Older experiments, kept as working traces.

Research projects, interactive tools, and LLM experiments from earlier work. New AI infrastructure case studies will join this archive as public material becomes available.

how I build

Agents need taste, traces, and operating context.

01

Make invisible systems observable

Logs, tests, and telemetry become useful only when humans can see what changed and why it matters.

02

Build agents with traces

Good agents should leave behind plans, tool calls, uncertainty, and enough evidence to audit their decisions.

03

Explain before optimizing

The fastest way to improve a workflow is often to draw the system clearly enough that everyone can point at the bottleneck.

field notes

Writing from the build floor.

Notes on agents, automation, data tools, and the parts of engineering that get more interesting when they become visible.
