TWO SIDES, ONE SYSTEM
For the client
  • — Guided intake maps your case before you pay anyone
  • — Compare verified consultants by country and visa type
  • — Track every milestone, document and appointment in-app
For the consultant
  • — A real CRM: pipeline, cases, calendar, team roles
  • — Escrow removes the awkward money conversation
  • — Verified badge turns trust into distribution
THE HARD PART

Immigration data is passports, bank statements and biometrics. Trust is the product, not a feature.

Money that must not half-move.
Escrow is the whole product promise, so the state machine is the whole engineering problem. Every transition has to be idempotent and every webhook replay-safe — a transfer that half-completes is worse than one that fails outright. Disputes can freeze the flow at any point without stranding either side.

Row-level security, in practice
A client can't reach another client's documents or chat; a consultant can't see a case they don't belong to. Enforced in Postgres, not in the app layer — and trust fields stay unwritable from the client entirely.

Erasure that actually erases
Tenant isolation, row-level access and crypto-shredding for erasure — designed for KVKK and GDPR from the schema up, not bolted on before launch.
