Sylvain Pierson

I’ve been the person your store is missing.

For two and a half years I’ve been the director of technology at an 8-figure DTC brand in San Diego — the in-house owner of everything this site talks about. The Shopify–NetSuite–3PL stack and its 14 production integrations. A Salesforce Commerce Cloud to Shopify migration. A $1M logistics-provider switch with no downtime. The agencies, the app vendors, the Celigo error queue, and the Monday-morning ops rituals we automated away.

That brand side matters. Most consultants have only ever billed brands; I’ve been the brand — the one accountable when checkout broke during a launch, the one reading vendor invoices with a technical eye, the one who had to make marketing, ops, and engineering agree. That’s the perspective I rent out now.

Before that: engineering school in Paris (embedded systems — I’ve debugged both circuit boards and checkout flows), a master’s in program management, product roles at Parrot and Enedis, and freelance builds from a franchise management platform to IoT sensors. Plus a certificate in AI business strategy from UC Berkeley’s Haas School — which mostly taught me when not to use AI.

I’m also an FAA-certified private pilot. Flying and e-commerce systems reward the same habit: trust your instruments, run the checklist, and never ignore a small anomaly — because small anomalies compound.

French, bilingual, US-based. I work with US brands primarily; French and EU brands welcome — GDPR was part of my job, not a mystery.

I take a small number of engagements alongside my full-time role. Small by design — you get me, not juniors billing under my name.
