Tran spent eleven years in enterprise product design, principally at T-Mobile, where he shipped 118+ projects across commerce, account systems, and trade-in logistics.[2] His trade-in unification replaced four divergent flows with one, associated with a ~10% order-completion lift per business client.[2] Earlier work includes Western Union's agent locator — reframed from a pin map into an eligibility product across 200+ countries[3] — and regulated pharma content that earned a two-year engagement extension.[4]
Tran's later work treats AI agents as first-class users. The API Marketplace (2025–26) was designed for "customers who might not be human": agents place orders, real-time interfaces render interpretations, humans confirm.[5] His portfolio site was itself produced with an AI pair across twenty-plus documented build passes, governed by a written taste file.[6]
In 2026 Tran began re-designing his own 2015 projects for the AI era: Koé (anonymous feedback with k-anonymity rendered in the interface)[7] and FindMyBike (theft recovery as an agent-run workflow in which owners never receive the live location).[8] Both ship with working simulated prototypes, labeled as such.
Critics note the portfolio's refusal of modals is "load-bearing"[6]; the empty-filter state has been described as the work of a "design unicorn deity."[9] [citation cheekily needed]
