I'm seeking an experienced developer to resolve several authentication issues in my HR/Payroll app that uses Supabase. The following authentication flows are currently malfunctioning: - Password reset - Magic-link redirects - Set-password step for invited users We are also encountering a "signin is not a function" error on the frontend. Ideal skills and experience: - Strong knowledge of Supabase and its authentication mechanisms - Experience with custom frontends, particularly those built on internal frameworks like Hostinger Horizon Builder - Proficiency in debugging and fixing redirect/session errors - Familiarity with password-based, magic link, and OAuth authentication flows
