Full-Stack Marketplace Security Audit

I'm seeking an experienced full-stack developer to audit and complete my Lovable/Supabase/Stripe Connect marketplace.

Key Focus Areas:
- Security: Prioritize user authentication, data encryption, and API security.
- Payment Integration: Ensure Stripe Connect is fully integrated and secure.
- Bug Fixing: Identify and resolve existing bugs.
- Testing: Conduct thorough testing to ensure launch readiness.
- Launch Readiness: Verify all components are functional and secure.
- Eventified uses Stripe Connect, with a 12% platform commission on transactions. Transfers and refunds are part of the existing payment flow. The developer will need to verify the current implementation and ensure everything is working correctly end-to-end.


Requirements:
- Proven experience with Lovable, Supabase, and Stripe Connect.
- Strong background in security protocols and vulnerability assessment.
- Proficiency in bug fixing and marketplace development.
- Excellent testing and verification skills.


Please provide examples of similar work done and a brief outline of your approach.

I have built a marketplace website using Lovable, Supabase and Stripe Connect. The platform connects customers planning events with local businesses such as cakes, balloons, florists, venues, photographers, caterers etc.

The website is already substantially built and functional. I'm hoping to change the aesthetics (Figma-style templates) with top-quality effort expected from the developer.
(I am NOT looking for someone to rebuild it from scratch or simply redesign it.)

I need an experienced full-stack developer to audit the existing codebase and get it genuinely launch-ready. The most important areas are Stripe Connect and the 12% transaction commission, payments/payouts, webhooks, refunds and payment security, Supabase/RLS and data protection, authentication, customer/business journeys, enquiries, messaging, notifications, marketplace/search, AI assistant and mobile functionality. Targeted promotions / future sponsored placements/ads.
Uses Stripe Connect, with a 12% platform commission on transactions. Transfers and refunds are part of the existing payment flow. The developer will need to verify the current implementation and ensure everything is working correctly end-to-end.

I need someone who can test the actual application thoroughly, identify anything that could cause problems with real customers or real money, fix genuine launch blockers, clearly explain what can safely wait until after launch, and ensure Figma-level aesthetics are achieved before final approval of deliverables.

I am particularly looking for strong experience with Supabase, Stripe Connect, marketplace/payment systems, security/RLS and full-stack development.

Please do not propose a complete rebuild unless you can demonstrate that the existing architecture genuinely cannot be made secure and reliable.

I would prefer to start with an audit/launch-readiness assessment followed by separately quoted fixes if required.
