Weihsuan (Wesley) Wong — Staff Software Engineer · Founding Engineer · Austin, TX

Engineering AI-native systems with a designer’s eye.

I build product systems across GenAI, UX, and frontend architecture — from enterprise AI platforms used by thousands of employees, to NFC payment experiences showcased globally, to travel agents built from scratch.

Blitz Code: 6K+ employees. Tap NFC: global stages. Youmi: zero-to-one AI pipeline. VPDS: four frameworks, one system. Armoury Crate: millions of users. Patent: inclusive design.

(02) — Working Notes

How I work

01

Ship the interface, not just the prototype.

I care about systems that survive real users, event pressure, and cross-functional ambiguity.

02

Make complexity feel usable.

My work often sits between AI, payments, design systems, and product operations.

03

Build from zero when needed.

From Flutter apps to AI pipelines to enterprise platforms, I like owning the full path from idea to shipped experience.

(06) — About

Behind the systems

I started at the edge of design systems, accessibility, and interactive demos — then moved deeper into product engineering, AI workflows, and full-stack systems. My favorite work sits in the messy middle: turning ambiguous ideas into usable products that can survive real users, real events, and real business pressure.

Outside the system

Outside of work, I'm usually exploring restaurants around Austin, playing table tennis or badminton, working on my lawn, or taking care of my pet fancy mice and satin mice. I like products with personality — and I try to bring that same sense of craft into the systems I build.
