Full-Stack Developer for Lovable + Supabase SaaS Bug Fixes & Ongoing Development

We're looking for an experienced Full-Stack Developer to help fix critical issues in our live SaaS booking application built with Lovable and Supabase. The platform serves service-based businesses by managing appointments, sending reminders, and collecting Stripe deposits. The app is already in production with active users, and we need someone who can troubleshoot and resolve the underlying issues rather than applying temporary fixes. If this project goes well, we'd like to continue working together on future enhancements and new features. Current tasks include: - Resolve a Supabase authentication issue causing users to be logged out when switching between the dashboard and booking calendar - Fix a Stripe payment bug that can result in duplicate deposit charges when appointments are rescheduled - Correct booking calendar time zone synchronization issues affecting users in different regions - Clean up duplicate and conflicting code generated during previous Lovable updates to improve maintainability - Review the existing codebase and recommend improvements where appropriate We're looking for someone who has: - Proven experience building or maintaining applications with Lovable - Strong knowledge of Supabase, including authentication, RLS policies, database schema, and debugging - Experience integrating and troubleshooting Stripe payments - Confidence working with an existing AI-generated codebase and identifying root causes of issues - Strong debugging, communication, and problem-solving skills - Ability to deliver reliable fixes within agreed timelines - Interest in an ongoing working relationship as the product continues to grow
