Hi, I'mYikai Liu
Full-stack PM × designer's eye. I ship 0→1 products end-to-end — research, architecture, React/Node/Python. Daily-driven OpenClaw multi-agent stack, hands-on benchmarking of frontier models, my own demos.
About Me
I'm 25, based in Hohhot, open to relocation. UQ MSc Interaction Design under the School of Computer Science (Group of Eight, QS Top 50), BA Marketing at Binhai College of Nankai University — a deliberately T-shaped path through the technical, design, and business sides of shipping product.
What I actually do well: take a product from 0 to 1, solo — from user research and architecture all the way to full-stack implementation. I've shipped real 0→1 business products and built LLM / multi-agent projects. I define the spec, write the code, talk to the users. That's the loop I'm best at.
Most of my days now go into AI tooling — benchmarking different frontier models into real production decisions and wiring up multi-agent workflows to run my day-to-day. My view: AI makes "building it" cheap, so PM value concentrates at both ends — defining the real problem, and judging whether it's good. My belief: the best AI PMs are also AI builders.

Indie AI Builder · Personal Practice
Built a customized multi-agent system on top of Claude Code — multiple agents with custom permissions and independent memory, wired into the Feishu (Lark) ecosystem via cc-connect. Continuously benchmark frontier models into a selection methodology; shipped multiple 0→1 deliveries solo: this portfolio, corporate landing pages, a chemical-sales visualization system, and a data-assistant agent.
MSc Interaction Design · School of Computer Science
QS Top 50, Group of Eight. Core: web full-stack (React / Django), physical computing, HCI. Two team-lead capstones delivered as Distinction-grade products: HD 7/7 (Smart Library) and D 6/7 (Memory Future Simulator), both publicly exhibited at the UQ campus showcase.
