Build C2C Exchange Integration on ShareTribe to Expand our Existing E-Commerce Businesses

I need a skilled developer/team to build a ShareTribe C2C exchange that integrates seamlessly with our existing B2C and B2B e-commerce platforms.

Key Requirements:
- Build a robust C2C exchange on ShareTribe
- Integrate with BigCommerce, Shopify, Quickbooks, ShipStation, SkuVault, and PHPBB
- Ensure scalability to accommodate our growing user base

Ideal Skills and Experience:
- Proven experience with ShareTribe
- Strong background in e-commerce integrations

- Strong problem-solving skills and attention to detail
- Ability to deliver within budget and on schedule

Looking forward to your proposals!
