AI Digital Twin for Online Coaches

Role: Full-Stack Developer (Lovable) & Product Designer Tools: Lovable, Supabase (Vector DB), RAG Architecture, Stripe API

The Challenge Coaches and creators often struggle to scale their time. The goal was to build a SaaS platform that allows creators to clone their expertise into an AI interface, enabling them to sell subscription-based access to their fanbase.

The Solution I engineered a fully functional SaaS application entirely on Lovable. To ensure the AI responses were accurate and reflected the specific coach's methodology (rather than generic AI advice), I implemented a RAG (Retrieval-Augmented Generation) system using Supabase as a vector database.

Zero-Hallucination Chat: Connected the Lovable frontend to a Supabase knowledge base, ensuring the AI only answers based on the coach’s uploaded data.

Subscription Gating: Integrated Stripe to handle monthly recurring revenue (MRR) for creators.

Marketing Site: Built the landing page (plussers.digital) using Gemini for copy and code generation, hosted alongside the app.
