Yanze (David) Wu.

ML systems, reliability
and reproducible evaluation.

I build and debug the infrastructure around machine learning. My focus is simple: understand the failure, test the fix, and make the evidence reviewable.

01 / Selected work

Systems I’m building.

Focused projects with inspectable code,
clear boundaries, and questions still to answer.

Research preview

CloudTune

Make ML runs easier to review.

An early ML infrastructure project for supervised fine-tuning on customer-operated infrastructure, failure recovery, and portable signed execution receipts.

  • Job contracts, runner ownership, and recovery
  • Evidence export and offline signature verification
  • Public demo; the application remains private

The demo uses synthetic execution with real signature verification. Customer validation and production qualification remain open.

Open source

AgentCI Guard

Inspect the workflows around AI agents.

An experimental TypeScript static analyzer for GitHub Actions workflows that run AI coding agents. It examines permissions and paths from untrusted inputs.

  • CLI and GitHub Action with SARIF output
  • Workflow reachability and permission analysis
  • Explicit diagnostics for incomplete analysis

Findings support human review. Detection accuracy has not yet been measured.

Transformers

Half-precision compiled execution

Fixed torch.compile failures in DETR-family position embeddings and added a compiled-dtype regression test.

Merged PR #47238
02

marimo

Completion fallback after analysis fails

Restored interpreter completion fallback when Jedi static analysis raises, with regression tests for failure paths.

Merged PR #10100

03 / Research

Measure what matters.

ML inference, evaluation,
and reproducible systems research.

I’m interested in how we evaluate inference changes against both performance and output-quality requirements. I am exploring Fall 2027 PhD opportunities in ML systems.

Earlier work at NYU WIRELESS connected material-aware 3D reconstruction with wireless simulation. I contributed to scene reconstruction, material labeling, and point-cloud processing.

Research & Engineering Profile PDF ↓

Public experiment: TraceBench — serving workload and measurement infrastructure with scoped experimental evidence. Its README defines the experimental scope and reproduction steps.

04 / Experience

Where I’ve worked.

CloudTune

Founder & Developer

Developing ML execution and evidence tooling: job contracts, runner coordination, failure recovery, and release evidence.

Current project

ArchAI

AI Research Intern

Built ComfyUI-based multimodal generation workflows and benchmarked open-weight models for internal research and demos.

May — Aug 2025

NYU WIRELESS

Teaching Assistant · ECE-1002

Feb — May 2025

Nanjing HuiJin Tech

Backend Systems Intern

Worked on Java and Spring Boot monitoring services, multithreading, Redis caching, and MySQL queries.

Jan — Dec 2023

05 / Field notes

Thinking through the details.

Let’s compare notes

A concrete problem.
A useful conversation.

ML systems research, infrastructure engineering, or a workflow CloudTune could help evaluate — I’d like to hear about it.
