Wenzhao Hu

Hi, I’m Wenzhao. I am a Systems Engineer and Architect specializing in high-performance computing and distributed state.

My career began in the browser, where I architected complex synchronization engines and rendering systems for massive-scale productivity suites like Univer and Lark. I have since pivoted to Agent & AI Infrastructure, applying my background in user experience, latency optimization and distributed architectures at NVIDIA.

Experience

NVIDIA — Senior Software Engineer (AI Infrastructure), 2025 - now

Building DGX Cloud Lepton using TypeScript & Golang.

DreamNum — Tech Lead & Architect (Univer), 2023 - 2025

Engineered a real-time synchronization engine based on Operational Transformation (OT) to solve complex distributed state consistency challenges.

Architected a plugin-based, isomorphic framework running across browser, Web Worker, and Node.js
Engineered a real-time OT-based collaboration engine supporting offline editing and multi-document sync
Designed an RPC layer for cross-thread and cross-process communication
Prototyped a multi-agent data analysis system using LangGraph, enabling intelligent insights within the spreadsheet engine.

ByteDance — Software Engineer (Lark Sheet), 2021 - 2023

Co-designed next-generation architecture for Lark Spreadsheets
Improved codebase maintainability and feature delivery velocity

Tencent — Software Engineer (WeCom Document), 2020 - 2021

Optimized initialization sequences to cut document load times by 10x (from >10s to <1s). Implemented high-performance canvas rendering and dependency injection systems to minimize memory overhead.

10x performance improvement on document loading (>10s → <1s)
Built high-performance canvas rendering pipeline
Implemented dependency injection system to reduce memory footprint
