Full Stack Dev Needed: Repair Firecrawl.dev, and Serper.dev Logic and AI Calling Module
We are building an AI-powered lead generation platform. The frontend UI is already designed (Lovable), but the backend logic, AI calling flow, and API handshake are not fully wired correctly.
We need a senior full-stack developer who can audit, fix, and complete the system so it works end-to-end.
This is not a design role. This is implementation + integration.
What the Platform Is Supposed to Do:
- Super AI Business Search: Search Google Maps / Yelp / Bing, run AI analysis on businesses, generate prioritized leads
- Agency Lead Finder: Identify businesses that need web design, SEO, ads, etc.
Critical Flow That Must Work:
- User must either enter their phone number to receive AI calls OR pay to use the calling feature
- System initiates an AI outbound call via API
- Phone number logic is single-number only for now (early stage)
- AI calling handshake via API must trigger correctly
- Backend must respond with valid JSON (currently breaking in production)
What's Broken / Incomplete:
- AI calling flow is not set up correctly
- API handshake logic needs fixing
- Auth & API endpoints sometimes return invalid responses
- Frontend (Lovable) is not properly connected to backend logic
- Phone number / payment gating logic needs to be implemented cleanly
Your Responsibilities:
- Review current setup (Lovable frontend + backend API)
- Fix API responses (JSON consistency, endpoints)
- Implement phone number capture + payment gate logic
- Correctly wire AI calling initiation via API
- Ensure system works end-to-end: User -> Input/Payment -> API -> AI Call -> Response
- Keep it simple and scalable (early startup stage)
Required Skills:
- Full-stack development (Frontend + Backend)
- API design & debugging
- AI calling / telephony APIs (Twilio, Vapi, ElevenLabs, etc.)
- Payment flow integration (Stripe or similar)
- Experience fixing broken or partially-built systems
- Comfortable working with Lovable or similar no-code/low-code tools
Nice to Have:
- SaaS startup experience
- Lead generation or CRM experience
- AI workflow automation
