Job Title: Full-Stack Developer (Lovable + Supabase) for "Flowy" – An AI Orchestration SaaS Project Overview: I am looking for a high-level Full-Stack Developer to build the MVP of Flowy, an AI Orchestration platform. Unlike simple AI wrappers, Flowy is a "GenAI OS" that allows users to create automated, multi-step workflows (Image, Video, Audio) using an AI Agent as a planner. The goal is to have a functional, high-performance MVP ready for investor demos and early adopters. Tech Stack: Frontend & UI: Lovable.dev (React + Vite + Tailwind). Backend/Database: Supabase (Auth, PostgreSQL, Edge Functions). AI Integration: OpenAI (GPT-4o as the Orchestrator), Fal.ai or Replicate (to access Luma, Kling, Flux, etc.), and ElevenLabs. Payments: Stripe (Subscription + Dynamic Credit-based consumption model). Key Responsibilities: The Flow Engine: Implement an agentic system where GPT-4o acts as a "Planner" to break down a user's natural language request into a sequence of API calls (e.g., "Script -> Voice -> Video"). Dynamic Credit Ledger: Develop a robust system in Supabase that deducts credits in real-time based on the specific cost of the model invoked (indexing API prices to maintain margins). Flowy Dashboard: Build a premium, minimalist UI/UX in Lovable that visualizes the execution of workflows step-by-step. Security: Use Supabase Edge Functions to handle all AI API calls securely on the server side. Asset Library: A clean gallery where users can manage their generated content and see the "lineage" (metadata/prompts) of each file. Requirements: Proven experience with Lovable.dev and Supabase. Expertise in integrating multiple GenAI APIs. Strong understanding of Serverless architecture (Edge Functions). Experience building SaaS with credit-based logic. Ability to deliver a "Pixel Perfect" UI that matches the high standards of tools like Lovable or Linear.
