About Me

I am an undergraduate in Intelligent Engineering from Tsinghua University's Class of 2021, with an interdisciplinary background across automation and design. I like to design and build things, and I see myself as a product PM who can also execute in code.

I served as Chairman of the Tsinghua Entrepreneurship Association from 2024 to 2025, built deep ties with alumni founders, companies, and investors, initiated Tsinghua's and arguably China's first university LLM hackathon in late 2024, and co-ran the Tsinghua AI Application Development Bootcamp with waytoAGI. I currently help run a developer community of nearly 1,000 people.

I have spent substantial time studying AI business models, and published "From the Steam Engine to AI: Why Every Technological Revolution Needs a Business Model Breakthrough" in CEIBS Business Review.

In September last year, I went to Shenzhen on my own to start a company, received incubation funding from Shenzhen InnoX Academy, and explored AI x children's drawing. The project did not work out, and I came back to campus to keep going deeper.

I am now working on indie projects / OPC, with a few small projects that I hope can reach PMF. I enjoy hackathons, and I still hold a perfect record across the four major hackathons I have joined so far.

I am looking for a breakout toC project in 2026, something like what Manus was to 2025, and I would love to join the right team to build a genuinely valuable product together.

Feel free to follow me on Xiaohongshu and GitHub, or just reach out to chat.

Before AGI arrives, I want to create a bit of real value for the world.

Tsinghua University

Intelligent Engineering and Product Design / Undergraduate

I am currently an undergraduate in Intelligent Engineering and Product Design at Tsinghua University, with an interdisciplinary background spanning automation and design. My GPA is 3.65/4.0, my GRE score is 330/340, and I was recognized as an Outstanding Student Leader at Tsinghua. My major coursework includes Data Structures, Principles of Artificial Intelligence, Object-Oriented Programming, User Experience Design, Interaction Design, and Product Design Practice, giving me systematic training across engineering execution, product design, and AI applications.

Project Experience

Oct 2025 - Mar 2026

Shenzhen InnoX Academy · LumiAI

Co-founder

LumiAI is an AI drawing companion robot designed for North American families with children aged 3 to 7, turning children's drawings into animated experiences to spark creativity and enthusiasm for making art. The product combines AIGC and multimodal interaction into a phygital experience and was incubated by Shenzhen InnoX Academy. I led user research, validation, and software development, covering in-depth interviews with more than 20 parents, user and market research, and competitor analysis, then translated those findings into product definition, interaction design, and implementation. I drove the AI drawing recognition, AIGC animation generation, and multimodal interaction modules from prototype to MVP, and used the software MVP to run user testing with the target audience.

Tsinghua University Institute for AI Industry Research (AIR) · DeskMAS

Multi-agent Researcher

This project explored multi-agent collaboration by building a multi-agent software system inspired by Overcooked, then extending it into DeskMAS, a desktop multi-agent development and collaboration platform for ESP32-based robots. The goal was to connect natural language input to physical robot collaboration in an end-to-end loop at the intersection of HCI and embodied intelligence. The work covered multi-agent architecture design, shared state space, and communication mechanisms; I also led the V2 migration to ESP32, designed a standardized serial protocol and JSON command format to decouple high-level decision-making from low-level execution, and combined a top-mounted 720P camera, ArUco markers, A* global planning, and APF local obstacle avoidance to validate multi-robot localization and navigation.

Mar 2025 - Sep 2025

StarBridge - An LLM-Powered Wearable for Social Skills Training in Youth with Cognitive Disabilities

Project Lead

StarBridge is a wearable device built with multimodal perception and AI to provide personalized social guidance and adaptive training for adolescents with mild cognitive disabilities in real-life settings, helping them build independence and social confidence. I led a five-person cross-functional team, drove product definition, market analysis, and software implementation, independently built the parent-facing app across both frontend and backend, and developed an iOS prototype in Swift that integrated multimodal scene recognition, voice cloning, and RAG-based AI features. The project established a partnership with the Rongairongle community and received the Beijing Second Prize in the China-US Young Maker Competition.

Dec 2023 - Present

Tsinghua University Center for Business Model Research

Research Group Member

I research how business models evolve in the age of intelligent technologies, with a continued focus on leading AI companies and the industrial paths behind technological revolutions. My work includes business model research and case analysis, and I published "From the Steam Engine to AI: Why Every Technological Revolution Needs a Business Model Breakthrough" in CEIBS Business Review, using a business model lens to understand how technologies diffuse and become viable in practice.

Campus Experience

Jul 2024 - Jul 2025

Tsinghua University Entrepreneurship Association

Chairman

During my term, I led the association's strategic restructuring, organizational upgrade, and startup ecosystem building, introducing six strategic directions including AI, embodied intelligence, and global expansion, and shifting the association from a traditional student club toward a more systematic platform for frontier entrepreneurship. I led major events such as the Kunshan Cup, the Qingxing Cup LLM application challenge, and hackathons, helped projects secure close to RMB 100 million in aggregate financing, and saw the association recognized as one of the university's most beloved student organizations. At the same time, I built collaboration networks across companies such as ByteDance, Tencent, and Baidu, public and industry institutions such as the Beijing Robotics Industry Association and Zhongguancun Science City, and investment firms including ZhenFund and InnoAngel; I also launched the AI+X lecture series and co-led the AI Application Development Bootcamp with partners including waytoAGI and ByteDance's Juejin community, attracting more than 1,000 applicants and helping build the Tsinghua developer community.
