Business process automation

3D Print Quote Calculator: from uploaded model to production-ready Shopify order.

A Shopify-approved application built around a process I knew first-hand: inspect a customer's 3D file, calculate a defensible price, complete checkout, and keep the production file attached to the order workflow.

Problem

Custom 3D-print orders often begin with a slow manual exchange: receive a model, inspect it, estimate material and setup cost, answer questions, create an order, and later find the correct production file again.

Redesigned Process

The customer uploads a model, receives a visual and priced configuration, adds the quote to Shopify checkout, and the merchant receives both the order details and the original file needed for production.

My Role

I reconstructed the real operating rules, defined the workflow and acceptance criteria, directed AI-assisted implementation, tested edge cases, refined onboarding and took the app through Shopify review.

One Connected Operating Chain

The useful automation is not the calculator alone. It is the continuity between customer intent, commercial rules, payment, and production.

  1. 01Upload the 3D model
  2. 02Analyze geometry and volume
  3. 03Apply material and pricing rules
  4. 04Complete Shopify checkout
  5. 05Retrieve the file for production

Rules, Exceptions & Guardrails

Most of the work lives in the cases a simple demo ignores.

Commercial rules Material density, infill, setup fees, quantity, merchant pricing, and currency must produce one consistent checkout amount.
Operational continuity The production file, selected options, calculated quote, and Shopify order must remain connected after payment.
Guardrails File validation, storage limits, price enforcement, privacy, billing state, and merchant configuration are handled explicitly.

Hiring Translation

This is the clearest bridge between my operating background and business process work.

Investigation Reconstructed a process from eight years of quoting, producing, shipping, and supporting custom 3D-print orders.
Implementation Turned the process into requirements, edge cases, validation rules, testing routines, merchant controls, and a working Shopify flow.
Outcome ownership Followed the work beyond the interface through checkout consistency, file retrieval, security reviews, documentation, and Shopify approval.

Hiring-Relevant Proof

The product demonstrates how I work: understand the actual business process, find where it breaks, make the rules explicit, design a better workflow, and stay with the implementation until customers and operators can use it end to end.
