PROJECT: Migrate Existing Lovable ERP App to External Supabase + Stabilize Architecture We have already built a working operational ERP system using Lovable + Supabase for a packaging manufacturing company. Modules already built: * Quotations * Proforma Invoices * Orders & Jobs * RFQ * Purchase Orders * Vendors * Dispatch * Costing * Workflow * User Roles * Mobile PWA Current issue: The project is still partially tied to Lovable Cloud backend/auth architecture, causing: * JWT/auth token mismatch * invalid token errors * deployment conflicts * mixed environment issues * stale cache/service worker problems We DO NOT want to rebuild the app. We want to KEEP the existing codebase and migrate/stabilize it properly. YOUR JOB: 1. Fully detach app from Lovable Cloud backend dependency 2. Connect app ONLY to our external Supabase project 3. Fix auth/JWT architecture 4. Remove old Lovable auth broker logic 5. Configure clean env variables 6. Stabilize deployment via GitHub + Cloudflare/Vercel 7. Clean stale caching/service worker issues 8. Ensure mobile PWA and desktop remain synced 9. Preserve all existing workflows/modules/UI 10. Help productionize architecture IMPORTANT: * This is NOT a redesign project * This is NOT a rebuild project * This is architecture cleanup + backend migration * Operational consistency is critical STACK: * Lovable frontend * TanStack * Supabase * GitHub * Cloudflare/Vercel YOU MUST HAVE EXPERIENCE WITH: * Supabase auth * JWT * RLS policies * Vercel/Cloudflare deployment * PWA/service workers * TanStack * React architecture cleanup * Migration from managed backend environments Please share: * Similar projects * Supabase experience * Architecture/debugging experience * Approach you would take * Estimated timeline This is a long-term opportunity if work quality is strong.

With my over 9 years of experience, I am confident in my ability to resolve the issues plaguing your ERP system. Having successfully completed several similar projects using Supabase, TanStack, Vercel and Cloudflare; I have developed substantial expertise in Supabase auth, JWT, RLS policies, Vercel/Cloudflare deployment, PWA/service workers and React architecture cleanup. I understand that this is not a rebuild project but an architecture clean-up and backend migration. My approach would be to carefully untangle your current architecture from Lovable Cloud backend by removing all the old Lovable auth broker logic, configuring clean environment variables and connecting only to your external Supabase without losing any existing functionality or UI. To ensure operational consistency and avoid further deployment errors, the use of GitHub, Cloudflare and Vercel will be appropriately optimized. My primary aim is to stabilize your system by fixing the auth/JWT architecture issues, eliminating token mismatch and mixed environment conflicts while ensuring that both your mobile PWA and desktop remain perfectly synchronized. Understanding that productionization of the new architecture is crucial for you, I would pay precise attention to detail throughout the project to guarantee a seamless post-migration workflow. Given this opportunity, I promise to provide you with nothing less than satisfactory results. Thank you for considering me for this task.

Hey, Sahanaj here. I can take this on. This is a classic “clean migration + auth repair + deployment stabilization” job, not a rebuild. I’ve worked on Supabase migrations, JWT/auth fixes, RLS policy debugging, and React/TanStack architecture cleanup where apps were partially locked into managed backends and needed full external Supabase control without breaking existing workflows or UI. My approach: First, isolate and remove Lovable auth dependency safely without touching UI or business logic. Then, rebuild clean Supabase auth flow with proper JWT handling and RLS alignment. After that, fix deployment, env configs, and service worker cache issues to stabilize PWA behavior. Finally, verify all ERP modules end to end with production style testing. Timeline is 3 to 6 days for full stabilization depending on codebase complexity. This is well within my experience. Relevant Supabase migration work can be shared on request.

Having successfully accomplished such tasks in the past, I would apply similar principles here; detach the app from Lovable Cloud backend smoothly, connect it flawlessly to your external Supabase project thus ensuring all workflows/modules/UI remain intact as it should. For me, creating a scalable digital solution is much more than writing code; it’s about understanding your business goals, respecting timelines without compromising on quality and delivering measurable results. The long-term opportunity that you offer aligns perfectly with my commitment to driving exceptional performance in every project that I undertake.

Hello, I have experience with React/TanStack, Supabase auth, JWT handling, deployment stabilization, and PWA architecture cleanup. I understand this is not a rebuild but a migration and stabilization project. I can help fully detach the ERP from Lovable backend dependencies, stabilize Supabase auth/JWT flow, clean environment conflicts, fix service worker/cache issues, and ensure reliable deployment via GitHub + Vercel/Cloudflare while preserving all existing workflows and UI. I’d first audit the architecture, identify dependency conflicts, then systematically stabilize auth, deployment, and caching layers. Best regards Gaurav
