Portfolio
Selected projects, technical experiments, and a few pieces told in depth.
Sam: your NZ driving practice app
The project I point to when someone asks to see AI-assisted development. A React Native simulator for New Zealand's full-licence test, built with AI deliberately and held to ADRs, falsifiable exit criteria and 254 deterministic tests. An AI examiner directs the drive by voice and closes with an NZTA-modelled verdict.

Nómina Account Upgrade — BBVA México
Modular in-app flow that takes a payroll customer from an N2 account (capped at 3,000 UDIs of deposits a month) to a fully documented N4, collecting ID, proof of address, KYC, tax residency and beneficiary as five independent, resumable modules inside the bank's internal Web Components stack.

SIM Distribution Portal — Bait (Walmart México)
Role-aware B2B console for Bait's MVNO distribution channel: batch SIM inventory moving down a three-tier reseller chain, carrier operations on the line (activation, area-code change, number portability) and a server-driven permission tree that drives navigation, route guards and write access alike.
