Backend Development for Twinoria SaaS

Description:
We are a Switzerland-based AI SaaS startup building Twinoria — a multi-tenant CRM with Tasks, Contacts, Files, Automations, and a dockable AI Twin overlay.
The frontend is complete in Lovable (Next.js/React + Tailwind + shadcn/ui).

This $400 paid pilot will deliver a working backend + AI foundation for Twinoria. Successful delivery may lead to long-term, higher-paid work.

Pilot Scope:

1) Auth & Orgs – Multi-tenant org/team creation, invites, roles (Owner/Admin/Member), server-side access control.

2) Contacts – CRUD, CSV import (5k rows) with validation, search, tags, export.

3) Files – Folder upload to S3 with signed URLs, preview, basic versioning.

4) AI Twin (MVP) – Dockable overlay with one safe bulk action (dry-run + confirm + audit log).

5) Docs & Observability – OpenAPI docs, Sentry FE/BE, README + Loom demo.
