HeyKIVI AI Video Platform: Enhancement and Maintenance

Project: HeyKIVI – AI video communication platform (MVP completed), now moving into post-MVP scale-out.

Main goals:

Implement multi-tenancy + feature entitlement (customers only see their own use cases/features) based on Admin UI.

Deliver continuous new use cases (frontend tile + backend workflow + HeyGen integration).

Provide ongoing platform maintenance (bugfixing, hardening, small improvements).

Pricing model:
Fixed package for multi-tenancy/entitlements.
Flat rate per new use case (continuous stream, varies by customer).
Hourly rate for anything beyond these two fixed scopes.

Tech stack: TypeScript, Next.js (API/backend), React 18 + Vite (frontend), PostgreSQL + Prisma, Docker Compose, Nginx, MinIO (S3), GitLab CI/CD, hosted on Hetzner (EU/Germany).

Key responsibilities: backend auth/authorization patterns (RBAC/ABAC), tenant isolation in DB queries/services, schema + API extensions, frontend entitlement enforcement, HeyGen workflow integration, deployment/CI improvements.

Ideal freelancer: proven multi-tenant SaaS experience, strong TS full-stack, Prisma/Postgres, Docker/CI/CD; HeyGen/video pipeline experience is a plus.

Collaboration: long-term; deliverables split into milestone package + recurring use-case deliveries + ad-hoc hourly support.
