02 / System

I build the connections between commerce, ERP and operations.

I started in web development and moved deeper into the systems behind ecommerce — APIs, ERP integrations, automation and infrastructure. Most of what I work on now sits between customer-facing commerce and the operational systems that keep it running.

The problems I like most cross system boundaries, where the hard part isn’t the code — it’s understanding how a business actually operates before deciding what to build.

EXPLORE THE SYSTEM
  • 01

    Storefront

    Miva Merchant and Shopify — templates, components, checkout and the commerce surface customers actually touch.

  • 02

    Marketplace

    TikTok Shop orders resolved against real customers and SKUs before anything is written anywhere.

  • 03

    ERP

    NetSuite as the system of record — sales orders, shipments, invoices, items and customers over REST and SuiteQL.

  • 04

    Automation

    Scheduled work that reconciles rather than assumes: dry runs, hidden keys, and a human decision where it matters.

  • 05

    Infrastructure

    PM2 processes behind Nginx on Linux, plus Docker images for the platform work.

  • 06

    Monitoring

    Health and status endpoints that tell an on-call human whether something is running or actually working.

03 / Selected work

Three of six systems

Chosen for breadth —
integration, platform, frontend

01 Ecommerce ↔ ERP Integration Systems integration · 2026 · Private production system Replaced a paid middleware subscription with a Node.js integration I designed, built, deployed and still run — five sync flows between Miva and NetSuite. 04 Multi-Tenant Commerce Platform Platform engineering · 2026 · Live for verified merchants Order protection for multiple merchant storefronts on one codebase, with tenant isolation enforced per query rather than by convention. 03 Storefront Design System Commerce frontend · 2026 · Public storefront A from-scratch component system for a live, revenue-generating Miva storefront, rolled out page by page with the legacy templates left untouched.

The title covers the ecommerce operations side; day to day the work is systems engineering — designing and running the integrations, automation and tooling that sit between the storefront and the systems behind it.

ABOUT / EXPERIENCE
06 / Lab

Where the parts come apart

Experiments — not production systems

  • Experiment

    Packet field

    The Core’s processing cells, responding to a pointer.

  • Motion study

    Type in motion

    Per-character staggering, the same grammar the Core separates with.

  • Prototype

    Timing playground

    Duration and easing, side by side, so the tokens can be felt rather than read.
