You will get Fix broken Shopify/WooCommerce integrations
Top Rated
Project details
A broken integration can instantly disrupt your e-commerce operations, causing failed checkouts, lost orders, out-of-sync inventory, and frustrated customers. I provide rapid diagnosis, troubleshooting, and reliable repair for third-party integrations, custom APIs, and automated data workflows across both Shopify and WooCommerce.
Whether your store is struggling with failing webhook payloads, disconnected payment gateways, sync errors with your ERP or CRM, or third-party app conflicts, I pinpoint the exact root cause and implement clean, durable fixes. My process begins with an in-depth audit of API logs, authentication tokens, rate limits, and data pipelines to ensure no live store records are compromised during the repair.
I resolve issues across REST and GraphQL endpoints, fix broken real-time inventory triggers, repair warehouse fulfillment connections, and restore seamless communication between your store and external platforms. Every fix is thoroughly validated with sandbox testing and simulated live transactions to ensure total data consistency, zero latency bottlenecks, and uninterrupted sales going forward.

Some businesses want to improve their existing systems. Others are ready to use AI automation to save time and work more efficiently.
No matter where you are in that journey, I can help. I am Jeroen, founder of Brightness Group in Amsterdam.
For more than 18 years, I have been helping e-commerce businesses and SaaS companies build and grow their digital products. I work on Shopify and WooCommerce stores, custom Laravel applications, and AI-powered automations that solve real business problems and make day-to-day operations easier.
Shopify & WooCommerce Development
▸ Shopify store setup, custom theme development, and Shopify Liquid coding
▸ Custom Shopify app development and Shopify Plus customization
▸ WooCommerce store development, custom plugins, and performance optimization
▸ Store migrations - WooCommerce to Shopify or platform-to-platform
▸ Headless Shopify (Hydrogen) and headless WooCommerce builds
▸ Connecting your store to payment gateways, shipping tools, and third-party platforms - set up correctly from day one
Laravel Backend Development
▸ Custom Laravel web applications, SaaS platforms, and admin dashboards
▸ Laravel API development - REST APIs, webhooks, and third-party integrations
▸ Backend logic for e-commerce stores that need functionality beyond what Shopify or WooCommerce supports natively
▸ CRM, ERP, and payment gateway integrations (Stripe, Mollie, PayPal, Salesforce)
▸ Database architecture, performance optimization, and legacy system rebuilds
▸ Vue.js and React frontends connected to Laravel backends
API Integrations & Workflow Automation
▸ Multi-system integrations - Shopify, WooCommerce, CRM, ERP, inventory, and payment systems kept in sync
▸ Webhook setup and event-driven architecture that holds up under real load
▸ Automation workflows using n8n and Make - eliminating manual steps between your store and your tools
▸ Fixing broken integrations - order sync failures, inventory mismatches, data inconsistencies
▸ Data migration from older or loosely structured systems
AI Integration & Automation
▸ ChatGPT and Claude API integration into Shopify stores, WooCommerce, and Laravel applications
▸ AI agents that handle repetitive tasks - order follow-ups, support triage, inventory alerts
▸ LLM-powered features - smart product search, automated tagging, dynamic content, and recommendations
▸ Connecting AI to your real business data so responses and actions are accurate, not generic
▸ Intelligent workflow automation - reducing manual work across your store, team, and tools
Most clients come to me for one of three reasons. They want to build something from scratch, improve a system that is not working well, or find practical ways to use AI in their business.
Before starting any project, I take the time to understand the business, identify the real problems, and recommend the right solution. My goal is to build something that works well today and continues to work as the business grows.
I do not try to be the cheapest option. I focus on delivering results and building long-term relationships. That is why many of my clients come back for future projects.
