01 / How I help

Strategy that survives contact with the code

Business sense with technical teeth.

I start with the commercial problem, look at what customers run into, then get into the system that runs it.

For established companies, leaders, and teams

Consulting

Bring me the growth target, the stalled project, the store that stopped converting, or the technical decision nobody wants to own. I find where the leverage is, turn it into a plan with dates, and stay on until it ships.

+AI strategy + adoption
+Shopify + ecommerce
+Lead generation
+Conversion + experimentation
+Technical architecture
+Product engineering
+Code audits + cleanup
+Security, PCI + accessibility

Workshops and advisory retainers are available inside an engagement when they help. They are not a separate menu.

05 / Code you can trust

Deslopify, then harden

AI wrote a lot of code. Someone has to understand it.

Generated features, rushed integrations, and copied patterns pile up fast. I read the code, work out what it really does, cut the slop, and make sure what ships is secure and accessible.

Deslopify the codebase

A senior pass over AI-generated and rushed code. Dead weight comes out, the shortcuts that break later get fixed, and your team ends up with a system it can reason about.

+Code review of AI-assisted work
+Refactoring and dead-code removal
+Patterns your team can keep using

Understand the stack

I read the frameworks, data flow, integrations, and performance underneath the output, then tell you in plain language where the risk sits.

+Architecture and dependency review
+Performance and data-flow audit
+Plain-language findings for leadership

Secure it, including PCI

Payment flows, secrets, dependencies, and access patterns checked against PCI DSS and the attack paths that get used in practice.

+PCI DSS scope and payment-flow review
+Secrets, auth, and dependency hygiene
+Prioritized remediation plan

Make it accessible

WCAG audits and fixes for keyboard, screen readers, color, and forms, so the site works for everyone and holds up when legal or procurement asks.

+WCAG 2.2 audit
+Keyboard, screen-reader, and form fixes
+Guidelines so it stays that way

06 / Who you're working with

Fifteen years of building things that make money.

I've spent 15+ years building ecommerce platforms, product experiences, and marketing technology. My favorite moment is when a plan on a slide turns into a working system with numbers behind it.

I've also started, grown, and sold a company and a couple of apps of my own, so I understand growth from the owner's side of the table. I live in Austin with Cheddar and Pecorino, two corgis with strong opinions about meeting schedules. I listen, challenge weak assumptions, explain the technical tradeoffs, and stay close to the results.

Strategy, code, and the results to show for it.
