Serverless Backend/API Engineer Needed

Build a small backend service that generates order-specific, tokenized links for customers to submit personalization data (name, gender, skin tone, hair note) and upload a photo. The system stores submissions, calls an image-processing API (face-swap + hair color/hairstyle), and returns a downloadable PDF built from a template. Minimal UI; function over form. No web design needed.

Goals
1. Secure, per-order intake flow
2. Reliable image-API integration (pluggable provider)
3. Automated PDF generation & delivery link
4. Simple admin view to review submissions

Scope of Work (Core)
• Tokenized per-order links: Unique links (e.g., signed JWT/HMAC) tied to an order ID.
• Intake form (minimal UI): Fields—name, gender, skin tone, hair note; photo upload.
• Storage: Save metadata & files (DB + object storage).
• Image pipeline: Call external API for face-swap and hair color/style; handle async/polling & failures.
• PDF generation: Produce a single PDF from our template and store it.
• Email/Delivery: Email a secure download link to us (and optionally the customer).
• Admin view: Lightweight table/list to see submissions, statuses, links.
• Docs & Handoff: Git repo, README, .env.example, and a 3–5 min Loom demo.
