Fix livekit egress recording & encrypted s3 upload for wound care consult app

Category: Web Development

Budget: 1900–1900 USDC

We run a remote wound care follow-up service for post-op surgical patients in rural clinics. Our web app is built on Next.js 14 (App Router), Supabase (Postgres + Auth), and LiveKit Cloud for WebRTC video visits.

We need an engineer to wire up automated server-side composite recording via LiveKit Egress and route the MP4 output directly to our AWS S3 bucket with KMS server-side encryption. Right now, room metadata writes to Supabase on disconnect, but the egress webhook fails silently on multi-party room closes, and uploads stall if a provider drops unexpectedly.

Our state Medicaid pilot starts June 15th, so we need this completed and tested by June 5th for compliance sign-off.

Deliverables:

• LiveKit Egress webhook handler in Next.js Route Handlers with full payload signature validation
• Reliable composite MP4 recording pipeline exporting directly to encrypted S3
• Database updates writing final S3 object keys and duration metadata to our consult_recordings table
• Automated retry handling for dropped egress tasks

Code must include TypeScript types and pass our existing Playwright test suite.

Skills required

• Next.js
• LiveKit
• AWS S3
• WebRTC
• Supabase
• TypeScript

Milestones are funded into USDC escrow on Polygon before work begins.
