Tran, Steven Long —
ledger of work, 2015–2026

T-Mobile inverted its integration model: stop building bespoke flows, open the system. Designed legible to enterprise developers and to the AI agents ordering on their behalf — interfaces verify, humans confirm.

Plans live on a map AND a clock; every tool shows one. Compas links them — drag either surface, the other reacts, the zigzag shows its time and money cost before you commit. Five field conversations in, bias footnoted.

Anonymous feedback rebuilt for a world where AI can synthesize candor and identify writers. Three rules: five voices before visibility, paraphrase over quotes, submitter confirms meaning survived. Working simulated prototype embedded.

The agent files the serial-numbered police report, verifies sightings by photo match, preps insurance — owner approves each step. The live dot routes to police, never to the owner. The paternalism trade is named, not hidden.

One shared flow instead of four forks; spreadsheet bulk upload that met legacy formats where they were; a modal argument lost well. Roughly 10% order-completion lift per business client.

A pin map reframed as an eligibility product: payout limits, services, and hours on the result card itself, across 200+ countries and 40+ languages. People trust money interfaces that tell the truth early.

Sixteen weeks, every pattern defensible in writing, research designed so the client could re-sell decisions internally. A two-year extension earned on the result.

A written taste file that wins every argument, a pass-by-pass build log with the failures kept in, and documentation excerpts as exhibits. The deliverable demonstrates the method.
