My credentials: Adobe-Certified Magento + Hyvä developer. 7+ years of luxury DTC builds (watches, jewelry, high-value collectibles) since 2019. Worked Riskified, Signifyd, Sift integrations; built authenticator NFC workflows; integrated Brinks + Malca-Amit shipping modules; navigated Rolex / Tudor AD portal politics with multiple dealer clients. Public Upwork track record (200+ reviews, $50k+ in luxury-DTC engagements). The patterns that survive contact with a $50k order are different from the patterns that survive $50 t-shirts, I’ve made every mistake at low-cost engagements so you don’t make them at $50k AOV.
