Who We're Looking For

Someone who doesn't just write code but understands business processes — able to take a real customer problem (inventory sync, complex checkout, ERP integration, business automation) and turn it into a stable, smart, maintainable solution.

Bonus if you've already built: SaaS systems, CRM systems, complex automations, Shopify Apps, Shopify Functions, system integrations, AI tools, ERP sync systems, backend infrastructure for business systems.
