Full-Stack SaaS Developer for LeadHive

I’m looking for an experienced full-stack SaaS developer with n8n automation expertise to build LeadHive, an AI-powered lead recovery platform for solar installation businesses. The project includes CRM integrations, automated personalized SMS/email follow-ups, interactive customer quotation pages, and a business dashboard. I already have a working frontend prototype and need help turning it into a secure, scalable, commercially viable SaaS product, starting with a cost-effective MVP. The ideal freelancer can build a reliable backend, implement automation workflows, and help create a product that is ready for launch.
