Finding the signal in
information asymmetry.
I’m Chenze Zeng, an aspiring AI product manager. I turn ambiguous user and data problems into practical products—from research and data pipelines to launch and iteration.

What I do
Product thinking, grounded in evidence.
I am drawn to AI, B2B, and data products—places where clearer structures and feedback loops make decisions easier.
Data
Make information usable
Work from collection and cleaning through labeling, quality control, and analysis to uncover patterns users cannot yet see.
Execution
Deliver end to end
Move from the first prototype to UAT, launch materials, and the feedback needed for the next iteration.
AI-native workflow
Use AI as leverage
Build with RAG, automation, agent workflows, and APIs while remaining accountable for the product decisions around them.
Selected work
Projects that delivered outcomes, not just prototypes.
Each case began with a concrete gap in information, workflow, or user understanding.
Featured project · 2025.12—2026.04
Graduate Employment Destination Explorer
University employment records were available only as unstructured lists, making destination patterns hard to understand. I independently took the product from 0→1: structured 20,000+ records across 34 schools, conducted 12 qualitative interviews, made six key data-design decisions, and led the initial launch. Three on-campus sessions produced a 43% event-to-visit conversion; the site reached 203 UV in its first month, and 58% of surveyed users said it helped calibrate their understanding of career outcomes.

Qiaoji AI Vocabulary Cards
Led an eight-person team that labeled data for an NFC-card, mini-program, and spaced-repetition learning system. Delivered 3,500+ labeled words with 96%+ dataset accuracy and a 240% productivity improvement, then transitioned into a product management role and wrote PRD v2.0.
Workflow automation · 2026
HR Contract-Signing Automation
Designed and independently delivered an automated workflow connecting Feishu Bitable with the Fadada e-signature API, including status polling and result write-back. The complete flow passed UAT before handover.
Personal infrastructure
Personal Knowledge-base RAG
Built a retrieval system over course materials, public writing, and ebooks—from collection and cleaning to structured ingestion and retrieval. The index now covers 3,565+ pieces of content.
Journey
A record of building momentum.
A selection from an ongoing weekly reflection practice—projects, experiments, and the moments that changed my direction.
Started at Chongqing University
Entered Chongqing University through its broad-based Engineering and Energy track, later specializing in Industrial Engineering, and started a self-training system around reading, communication, and consistent weekly reviews.
Joined Qiaoji as Data Lead
Joined the AI vocabulary project as Data Lead and led the team’s data-labeling work before transitioning into product management.
Assistant Management Trainee, Career Center
Supported a job fair serving 1,000+ employers and 20,000+ graduates. A Python automation reduced ledger-entry workload by 60%.
Built the employment explorer independently
Conducted research, structured the data, designed the experience, and launched a product that made graduate outcomes easier for students to understand.
Product Manager Intern, Muchen AI
Worked on a dataset platform from 0→1 and delivered an HR contract-signing automation that completed a live, paid e-signature transaction.
Building stronger product judgment
Preparing two end-to-end portfolio cases while looking for opportunities in AI, B2B, and data product management.
Craft
The tools are only useful when they close the loop.

Writing & learning
Consistent writing is a form of product research.
I write to explain how I think about products, growth, work, and the systems behind them.
Writing
20,000+ reads on a product essay
I write about product thinking and growth, including “Good Products and Bad Products: Short-term Pleasure or Long-term Options?” and a self-developed 3L model for evaluating large technology companies.
Reflection
70 weekly reviews and counting
Since my first week of university, I have maintained structured reviews of what I did, what I learned, and which judgments turned out to be wrong.
Podcast
Independent Variable
An interview podcast examining choices, costs, and outcomes. Every conversation asks: what variable changed, what did it cost, and what lessons can others apply?
Learning system
Evidence over intuition
I keep learning across cognitive science, systems thinking, product practice, and long-term decision-making, then test those ideas against real projects.
“Build a system that lets you see what you would otherwise miss.”My working principle: make the problem clearer, make the next action easier, and leave behind a feedback loop.
