We are seeking an experienced and senior Next.js developer to diagnose and resolve a critical bug in our existing project.

The ideal candidate will have a strong understanding of both technologies and be able to quickly identify the root cause of the issue and implement an effective solution. We require a thorough approach to bug fixing, including testing to ensure the stability and functionality of the application post-fix. Please detail your experience with Next.js and Supabase in your proposal.
