Long-Term Fullstack Dev for Backend Automation Platform (AI + WhatsApp)

---

---

We’re developing an internal platform to automate real estate insight delivery through WA, and we’re seeking a skilled Fullstack developer to own the development and long-term support of the system. We’re looking to: - Build a logic engine that turns structured property data into personalized GPT-powered insights - Deliver formatted messages to agents via WA for forwarding to clients (buyers, landlords, tenants) - Manage personalization logic, data ingestion, and an internal admin panel for operational control This is a self-contained backend system (no customer-facing UI), designed for internal use and automation. What we’re looking for: - Someone who can deliver the full scope of the initial system build (well-documented) - A developer who’s also open to a simple monthly support package for ongoing tweaks - Comfortable with GPT integrations, backend logic, admin interfaces, and WA API formatting We’ll provide full logic breakdowns, prompt samples, use case flows, and guidance — this is not an exploratory job, it’s a well-scoped build. **Structure:** a) One-time fixed price for building the full backend system b) Simple ongoing monthly subscription for maintenance and refinement Let me know if this sounds interesting, and I’ll share more structured detail on deliverables and timelines.
