Joined DreamNum after a roughly month-long break between roles. My focus is bringing Univer's industry-leading spreadsheet editing capabilities to agents: building spreadsheets for agents rather than iterating on the spreadsheet editor itself.

Joined seed-stage AI startup as founding engineering leader. Initially built B2B Sales Agent with LangGraph stack, then re-architected the core into Marco—a Rust-based Agent Runtime inspired by Codex/Pi architectures. Designed domain-agnostic runtime layers (Session, Tool Loop, Event streaming) with Domain Pack abstraction, built multi-Agent management patterns, and shipped production-grade K8s infrastructure.

Transitioned from enterprise CAD platforms to focus on cutting-edge AI infrastructure challenges. Architecting comprehensive AI stack (K8s + PostgreSQL + ClickHouse + RisingWave + Kafka + Qdrant) for enterprise e-commerce automation. Applied infrastructure optimization expertise to reduce memory usage from 200GB to 20-30GB and monthly cloud costs by 80%, achieving 99.95% SLA.

Promoted to CTO as company entered MiraclePlus (YC China) accelerator program. Led company growth from 4-person startup to 30+ team, scaling engineering from 2 to 20 people. Introduced Serverless processing with Knative for cost-efficient CAD model processing. Secured funding from prominent investors including Sequoia, ZhenFund, and MiraclePlus while driving revenue from zero to millions. As CTO, also contributed directly to business development, personally closing 5 enterprise clients.

Built modern development organization from ground up, transforming from ad-hoc processes to structured 2-week sprint cycles with comprehensive CI/CD pipeline using GitLab. Based on deep insights into customer needs for managing mechanical design project files, proposed and implemented Git-inspired version control system, developed in Rust for performance optimization. Established automated testing framework and trunk-based development, while migrating architecture from single-machine deployment to high-availability K8s clusters. Mentored 2 fresh graduates and 3 junior engineers, with team members later taking key roles at other companies.

Joined as employee #4 when company had only 2 technical staff total. Architected entire CAD platform from zero, focusing on 3D CAD model online preview functionality and simple single-file version control. Built EverCraft platform MVP using React and Next.js, delivering a complete minimum viable product loop that established the technical foundation for future development.

Developed data analytics modules for multi-store management system handling significant daily transaction volumes. Built reusable component library that improved development efficiency, resolved critical cross-browser compatibility issues enhancing user experience across IE9+ and modern browsers.
