01 / How I help

AI → better decisions → shipped growth ↘

Business sense with technical teeth.

I connect the commercial problem, the customer experience, and the system underneath it. Then I help your team ship the right thing.

For established companies, leaders, and teams

Consulting

Bring me the growth target, stalled initiative, ecommerce problem, or messy technical decision. I find the leverage, make the plan concrete, and stay close enough to delivery to make sure it works.

Workshops and advisory sessions sit inside a consulting engagement when they help move the work forward.

27 brands / work I helped ship ↘

The company I keep

Brands where the work had to perform.

Hands-on work across commerce, campaigns, platforms, and product systems.

Familiar names. Real work.

04 / Technical index

I can stay in the strategy room and read the code.

Technical expertise is part of the consulting, not a separate handoff. I can evaluate the system, work with the team, and understand what it will really take to ship.

The useful layer is where business intent survives implementation.

05 / The person doing the work

A one-person practice, on purpose.

I've spent 15+ years building ecommerce platforms, product experiences, and marketing technology. I like the point where a business goal stops being a slide and starts becoming a working system.

I live in Austin with Cheddar and Pecorino, two corgis with strong opinions about meeting schedules. The site is personal because the engagement is personal: I listen, challenge weak assumptions, explain the technical tradeoffs, and do the work with you.

Half strategy. Half code. Fully accountable.
