01 What I do

Three skill sets that rarely share a desk.

Sales and marketing win the orders, operations has to source and ship them, and AI should make all of it faster. I have run all three: as a COO, as a Director of Ecommerce, and as the person who builds the ERP and the agents.

02 Sales & sourcing

I started in sales. I never stopped.

Twenty-plus years in sales and management, B2B and B2C. I have sold, trained the people who sell, worked with the buyers at the biggest retailers in the country, and sourced products straight from the factories that make them.

03 AI practice

AI isn’t a slide in my deck. It runs my week.

I build the agents, connect them to the platforms businesses actually run on, and keep a person in charge of anything a customer sees.

01

AI agents

Agents that run on a schedule with a shared memory: they monitor ad platforms for changes, research prospects, draft outreach and posts, and queue everything for a person to approve.

02

MCP servers

Custom Model Context Protocol servers that give AI agents safe, scoped access to Shopify, Odoo, Meta, Google Ads, Amazon Ads, TikTok and GoHighLevel.

03

Business automation

ERP automations that check data, raise alerts only when something is really wrong, file documents and email reports on a schedule.

04

AI-assisted development

Integrations, plugins, apps and full websites delivered in a fraction of the usual time, then tested on real devices before anyone sees them.

Cart, affiliates, lab report lookup and a label studio that draws every product photo, on its own code base and database.

Billing, contracts and a client portal

AI agents with a shared memory

Scheduled agents that check every ad platform for changes each week, research prospects and draft outreach. Nothing goes out until a person approves it.

A 3D world for a services page

Floating islands for each service family, lit and flown through as you scroll, built in Three.js.

05 Now at PlantSwitch

Systems I built from the ground up.

A growing manufacturer needed one system instead of spreadsheets. I launched Odoo company-wide and built the custom pieces around it.

01

Odoo ERP/WMS rollout

One system for inventory, orders, purchasing and the warehouse, used by sales, operations, accounting and the overseas production team.

Odoo 18InventoryWarehouse
02

Shopify ⇄ Odoo integration

Built in-house to replace a paid connector. Online orders flow into Odoo, and payments recorded in Odoo mark the Shopify order paid.

ShopifyOdooCustom code
03

Import order & container tracker

Follows every overseas purchase order from confirmation to the warehouse door, checks that what shipped matches what was ordered, and flags what needs attention.

PurchasingLogistics
04

Demand forecast & run-out view

Customer forecasts by product and month, set against stock on hand and on order, so purchasing sees when each product runs out and when to reorder.

ForecastingPlanning
05

Leadership dashboards & sales reporting

Sales reported on what actually shipped, margin views for the people who should see them, a live back-order report and reports anyone can schedule to their inbox.

ReportingKPIs
06

Quality control & lab reports

Inspection forms with photo capture, and drop folders where lab test reports file themselves by category for the US team to review.
