About

I've spent my career creating and managing technology stacks for brands you'd recognize — Fendi, Frye Boots, J. McLaughlin, Havaianas, and plenty of others. The full technology stack: e-commerce sites, point-of-sale systems, order management, ERP integrations, you name it.

I wasn't just managing these projects from a distance. I was in the trenches designing architectures, building integrations, writing SOPs, and making sure everything worked 24/7.

That hands-on experience is what makes me effective today. I work with enterprise brands on their commerce technology strategy, helping them choose the right platforms, architect solutions that scale, and navigate complex transformations.

Experience

Head of Enterprise Solution Architecture, North America

Shopify

June 2022 — Present

Leading a team of enterprise architects who sit at the intersection of technical depth and business strategy. We work with Shopify's largest prospective customers — Fortune 500 retailers, iconic global brands — to design scalable solutions that prove what's possible on the platform. Part strategist, part technical advisor, part trusted consultant.

Technical Architect (Professional Services)

Salesforce

May 2020 — June 2022

I built enterprise cloud solutions for Salesforce's largest clients, focusing on operational efficiency and helping companies modernize their tech. This meant working directly with C-level executives on strategic decisions, developing technology roadmaps, and recommending best practices they could actually implement.

Senior Manager, Direct To Consumer Platforms — COE

Global Brands Group

Jan 2015 — May 2020

I led a three-person center of excellence responsible for the full technology stack across Global Brands Group's portfolio (20+ brands) of enterprise retail and e-commerce brands. My team owned architecture, implementation, and day-to-day operations — everything from platform selection to integration design to 24/7 support. We partnered directly with brand executives to build DTC roadmaps grounded in emerging tech rather than hype, identified where the business was leaving revenue on the table, and fixed it.

Enterprise Architect

J.McLaughlin

Jan 2014 — Jan 2015

I was the IT lead for the company's core platforms: Order Management (Order Dynamics), Demand Planning (ITR), and Point-of-Sale (Celerant). This meant overseeing the helpdesk team, keeping all IT systems running smoothly, and managing projects for new features and integrations.

IT Analyst

Havaianas

Jul 2013 — Jan 2014

I led Havaianas' direct-to-consumer launch by designing and implementing the IT infrastructure for their first six retail stores. I worked closely with store operations and design teams to create a replicable store footprint — a playbook that made opening new locations faster and more consistent.

Retail IT Analyst

M.X. Data

Nov 2011 — Jul 2013

I was the IT Support Analyst and Project Manager for a portfolio of luxury retail clients — brands like Lanvin, Burberry, Celine, Marc Jacobs, Fendi, GANT, Carolina Herrera, Jimmy Choo, Dover Street Market, and Comme Des Garcons.

IT Analyst

FENDI North America

Nov 2010 — Nov 2011

I was half of a two-person IT department managing all systems and hardware for FENDI's corporate offices and retail locations across the US and Mexico. I also worked closely with LVMH headquarters to roll out global IT initiatives.
