Next.js / PostgreSQL Developer — Fix One Bug & Finish Final 10% of Launch

I have a website built on Next.js/Vercel that is 90% complete and ready to launch. My developer went MIA and I need someone reliable to jump in and finish the job. The main blocker (must fix first): PostgreSQL duplicate key constraint error — "duplicate key value violates unique constraint photos_order_display_order_idx" — happening during photo upload/order submission. Orders are not completing as a result. Additional items needed after bug fix: Email template updates (logo, branding, sender name, delivery time) TOS and Privacy Policy copy updates Intake form field changes (add/remove questions, add opt-in checkbox) Order status page branding (add logo) Minor layout fixes (button alignment) Confirm auto-recharge working on AI services End-to-end test runs (Standard + Premium + deliberate failure) Go-live support Tech stack: Next.js, Node.js, TypeScript, PostgreSQL (Neon), Vercel, Stripe, Resend, fal.ai, Creatomate, EvoLink, Cloudflare R2, Inngest, Sentry What you'll have access to: Full GitHub repo access, all platform accounts in my name, all API keys in GitHub secrets. You are not starting from scratch — the codebase is complete except for these items. What I need from you: Reliability and communication above everything else. Daily updates. Fixed price preferred. Available to start immediately.
