Yori Coppens · E-Commerce & Backend Architecture

Freelance Technical Solutions Architect for e-commerce brands that have outgrown manual operations.

I design and build the backend systems mid-market and enterprise brands run on: Shopify Plus apps, custom serverless APIs, Akeneo PIM data pipelines, ERP integrations and multi-currency B2B order automation. 10+ years in e-commerce engineering — you hire me directly, no agency in between.

Expertise

The full stack between your storefront and your back office — designed, built and maintained by one person you can actually call.

E-Commerce Platforms

Full-store development on Shopify Plus — custom apps, Shopify Functions, checkout extensibility — plus enterprise platform management including legacy Magento.

  • Shopify Plus
  • Shopify Functions
  • Magento

API Development

Serverless APIs that connect systems never designed to talk to each other: signature-verified webhooks, boundary-level error handling, built to run unattended.

  • DigitalOcean Functions
  • Zoho Catalyst
  • REST & GraphQL
  • Webhooks

Automation & Middleware

Robust data orchestration with self-hosted n8n and Make.com: multi-currency B2B order flows, retry logic and dead-letter handling — pipelines that survive bad data.

  • n8n (self-hosted)
  • Make.com

PIM & Product Data

Akeneo PIM as the single source of truth for complex catalogs: multi-locale, compliance-sensitive content, automated publication to every sales channel.

  • Akeneo PIM

Enterprise Ecosystems

Deep integrations across Zoho and Odoo — connecting orders, invoicing and logistics (including UPS shipping APIs) into one automated flow.

  • Zoho CRM
  • Zoho Finance
  • Odoo
  • UPS API

Infrastructure & Tracking

Self-hosted Linux VPS architectures with Docker Compose, Caddy and PM2 — plus server-side, privacy-friendly tracking that keeps your marketing data accurate.

How I Work

Four stages, one point of contact. No handoffs, no surprises.

01

Intake & Discovery

I map the business problem before touching any tooling. What breaks, what it costs, and what a working solution actually needs to do.

02

Architecture Proposal

A written plan with the chosen stack, data flows, and trade-offs explained in plain language. You approve before a single line is written.

03

Build & Deliver

I build, test, and deploy. You stay informed with short updates — no jargon, no radio silence. Scope changes are discussed openly.

04

Handover & Support

Full documentation, a walkthrough, and a clear handover. The system is yours to run. I stay available for questions.

Ideal Collaboration

I provide a steady hand and take full ownership of the process, bringing calm and clarity to the project. Strategic decisions are based on what actually works — not on impulse, politics, or ego.

For me, collaboration works when it's built on transparency, mutual respect, and directness. No hidden agendas, no rigid hierarchies — just two equals focused on the outcome.

Case Studies

Real systems in production. Each project below replaced a manual bottleneck with infrastructure that runs itself.

Architecture flow: Professional → VIES VAT Validation → Shopify Plus GraphQL → Catalog + Terms → Email

Benfida (B2B healthcare e-commerce, Belgium)

Automated B2B Onboarding: Shopify Plus + Real-Time VIES VAT Validation

Problem
Shopify has no native solution for automated B2B approval flows. Every new professional application — pharmacists, doctors, therapists, wholesalers, and bookshops — required manual steps: linking the right price catalog per country, verifying the VAT number, reviewing company data, and setting payment terms. This created administrative delays and an increased risk of errors in VAT shifts and catalog assignments.
Impact
100% elimination of manual catalog links. Zero manual VAT checks for standard applications. Under 3 seconds from form submission to a fully configured Shopify B2B company.

Architecture flow: Shopify Plus → Make.com → Billit

B2B e-commerce brand (Belgium)

Automated B2B Invoicing: Shopify Plus Orders to Billit via Make.com

Problem
Shopify Plus has no native solution for Belgian B2B invoicing: off-the-shelf apps like Sufio work for simple B2C flows but break down the moment you add VAT shifts, 30-day payment terms, and international wholesale customers. Every order required a manual invoice in Billit — copy-pasting customer data, order lines, and VAT details — costing 6+ hours per week.
Impact
Invoice creation time dropped from ~8 minutes per order to zero. Zero billing errors since go-live. Finance team reclaimed 6+ hours per week.
