Senior Fullstack developer (Next.js, Supabase) - PT - EMEA/LATAM

About the company:

Real Growth is a marketing company that helps authors, coaches, and consultants turn their books and expertise into automated online sales systems. We're building a web platform that lets people do this at scale.

What you'll be working on:

Full stack web applications where a user uploads a manuscript or their content, and the system automatically generates a branded sales website — complete with payment checkout and automated email follow-up sequences. You'll also build AI-powered features, like an AI guide that walks users through a structured product experience. Day to day that means React/Next.js on the front end, a Postgres/Supabase backend, Stripe for payments, transactional email, and integrating the Claude API for the AI features.

Core stack / required skills:

• Next.js (App Router) and React with TypeScript
• Supabase (Postgres, auth, storage), including pgvector for embeddings
• Stripe integration (checkout, subscriptions, webhooks)
• Transactional email via Resend
• LLM integration via the Anthropic / Claude API
• REST/serverless API design and deployment (Vercel)

Nice to have:

Meta Ads API / data connector experience, retrieval-augmented generation (pgvector + embeddings), and a feel for clean, conversion-oriented UI.
