I build end-to-end digital products for luxury retail, SaaS, and B2B — Shopify storefronts with 500+ SKU data pipelines, fullstack apps with 40,000+ lines of production code, and developer tools deployed on edge infrastructure.

My focus sits at the intersection of clean UI, complex backend systems, and measurable business outcomes.

Migrated CDN to Cloudflare R2 and implemented GA4 analytics tracking. Dual collection engine (diamonds + gemstones), 360° spin viewer, metafield-driven cert embeds, localStorage wishlist with cross-section event bus.

Ricardo shipped our new storefront in six weeks on a stack we hadn’t used before. The 360° diamond viewer alone probably pays for itself twice a year.

He thinks about billing workflows the way our best PMs think about user flows. RIVET wouldn’t be shippable without him.

Signet’s HMAC tokenization pipeline went to prod with zero issues — the cleanest compliance infra we’ve touched.
