eCommerce, technology, and hands-on building

Twenty yearsin the weeds ofecommerce.

Started on OsCommerce, moved through Magento, then agency work on BigCommerce and Shopify. I work where tech and operations collide: untangling systems, planning cutovers, and keeping the work moving until it ships. No buzzwords required.

What I ship
Full-scale platform migrations, connected product data pipelines, and production systems designed to run cleanly on day one.
How I work
Ask direct questions, get into the details, establish clear ownership, and ship.

Things I've shipped.

A mix of client work, long-running commerce systems, platform migrations, and one personal project that means more to me than a normal portfolio piece ever could.

Agency

Keeping 20+ commerce clients moving

Netalico Commerce · eCommerce Consultant / TPM

Managed a portfolio of 20+ commerce clients across Shopify Plus, Magento / Adobe Commerce, and BigCommerce. Some needed a replatform. Others needed a problem solved before it turned into three more.

I worked directly with business owners and merchant teams, translated what they needed for developers, and kept scope, decisions, risks, and next steps visible. The job covered discovery, launch planning, training, analytics, and technical SEO, often across several accounts at once.

  • Shopify Plus
  • Client consultation
  • Technical requirements
  • Replatforming
  • Multi-client PM

Result: clients knew what was happening, why it mattered, and how to run the system after the project team stepped away.

In-house

Moving thousands of subscriptions without breaking continuity

Learner's Digest International · Technical Project Manager

Led the transition from Think to Chargebee for thousands of recurring subscriptions. When a system touches every customer and every renewal, data integrity is not cleanup work. It is the work.

I turned technical constraints into decisions for engineering, Marketing, Customer Service, and executive stakeholders. Daily Agile delivery, documented risks, and weekly SteerCo reporting kept the hard parts visible.

  • Chargebee
  • SaaS migration
  • Requirements
  • Documentation
  • SteerCo

Result: zero disruption to subscriber accounts or billing during a complete core system replacement.

Freelance

Helping merchants own and run the system

Freelance / Self-employed · eCommerce Consultant & TPM

I manage Shopify and BigCommerce platforms across their entire lifecycle. Beyond major replatforming projects, that means serving as the technical problem-solver on call: untangling product data in Salsify, diagnosing broken app integrations, and fixing the day-to-day operational snags that slow down a business.

Google Merchant Center feeds, analytics, technical SEO, and workflow audits all serve one purpose: make the business easier to find, run, and scale.

  • Shopify
  • BigCommerce
  • Salsify
  • App integrations
  • Technical operations

Result: merchants receive a stable system they can actually understand, run, and improve.

In-house

Running the stack behind two commerce brands

Hurricane Golf / Diamond Tour Golf · Senior Manager, IT & eCommerce

For 16 years, I owned the technology behind two commerce brands: 5,000+ SKUs, multiple marketplaces, Magento, Sage ERP, ChannelAdvisor, ConnectShip, CRM, infrastructure, and company-wide IT.

I led the move from QuickBooks to MAS 90 and later Sage 100, connected workflows across departments, served as the internal system architecture SME, and managed the migration to Amazon Web Services.

  • ERP integration
  • CRM
  • Fulfillment
  • AWS migration
  • Conversion optimization

Result: a connected commerce stack, plus affiliate work that increased conversions by 15%.

Side project

Building the archive my dad's collection deserved

Farm Diecast · Founder / Builder

Farm Diecast started with the John Deere collection I inherited from my dad, Jerry. I wanted to preserve the history behind the models and build the kind of reference site collectors actually need: specifications, current eBay pricing, sold history, and links to active listings.

I designed and shipped the edge architecture on Cloudflare: Astro 7 and API routes in one Worker, D1 and KV storage, analytics, email alerts, daily eBay Browse API syncs, and a read-only MCP endpoint for AI agents. The safeguards for shared stock numbers, price outliers, misleading listing ages, and missing cron registration are there because trustworthy data does not happen by accident.

  • Product strategy
  • Astro
  • Cloudflare Workers
  • eBay Browse API
  • Data quality
  • MCP

Result: a low-cost collector platform with monitoring and data-quality controls that keep the catalog trustworthy. Visit Farm Diecast (opens in new tab)

What matters to me.

  1. Stay close to the work

    I like leading, but not from a distance. I want to understand the system, the customer, and the details that can sink the plan.

  2. Make the complex clear

    The goal is not to sound technical. The goal is to help people understand the decision and what happens next.

  3. Say the hard thing early

    A risk does not improve while everyone politely avoids it. I would rather surface the issue while there is still time to act.

  4. Leave it usable

    A launch is not the finish line. The people who inherit the system should know how it works and feel confident running it.

Use AI as a tool, not a crutch.

Claude for technical work, Gemini for planning, and a continuous testbed for whatever ships next. AI makes me faster. It doesn't make the decisions, and it doesn't do the accountability.

Let’s talk

I have spent years leading teams, systems, and high-stakes projects. What still energizes me is getting into the problem, making something useful, and watching it work in the real world.
