Code
Systems that hold under pressure. We treat source code as a craft surface — typed, tested, readable at 2 a.m., honest about its trade-offs.
Precision is a form of respect.
I am Tianli Xu, and I build at the intersection of logic and feeling — where rigorous engineering meets deliberate design, and technology stays accountable to the humans it serves. Machines can generate; only people can mean.
Systems that hold under pressure. We treat source code as a craft surface — typed, tested, readable at 2 a.m., honest about its trade-offs.
Interfaces with a point of view. Grid-breaking layouts, typography with intent, motion that explains instead of decorates.
The non-negotiable center. Accessibility, privacy, dignity — the metrics that never show up on a dashboard but decide whether the work matters.
Intelligence as a collaborator, not a slot machine. We study, deploy and question learning systems — amplifying judgment rather than replacing it.
Hi, I'm Tianli Xu — friends call me Telly. I'm an independent engineer and designer who ships products end-to-end: idea, interface, infrastructure. From corporate websites to scheduling copilots, from nutrition tools to keyboard configurators — everything on this page was built by one pair of hands.
