About the Role

We are seeking a freelance developer to adapt our existing bespoke Shopify-to-Erply integration into an installable Shopify app that can support multiple store contexts: owned retail, B2B, and third-party logistics (3PL). The app should be built for long term maintainability and ease of deployment across different Shopify stores.

• Ensure the app is scalable and can be managed through our existing infrastructure on Google Cloud.

Tech Stack

  • Products / Variants

  • Orders / Fulfilments / Invoices

  • Inventory

  • Locations

  • Configuration

• Build admin configuration settings within the Shopify app UI to support retail, B2B, and 3PL variations.

• Handle authentication, store-specific settings, and Shopify App Bridge conventions.

• Collaborate with our internal dev team (Product Manager, Backend Developer, Frontend Developer).

• Set up deployment and CI/CD pipeline within GCP for production use.

Deliverables

• Fully functional, installable Shopify app

• Admin UI for managing context-specific settings

• Deployment guide and documentation

• Unit and integration tests

Collaboration & Communication

• JIRA for issue tracking and progress updates

• Code review and version control via GitHub

The Ideal Candidate
