A multi-tenant data platform for a US enterprise
A US client needed a robust data platform with strict tenant isolation, an SFTP ingest pipeline, and audit-ready logs. We shipped it with idempotent processing, row-level isolation, and unattended ops.

The build stack
Web platform
Next.js (Pages Router) + i18n + role-scoped routing
Data ingest
SFTP intake → idempotent processor → normalized schema
Database
Postgres + per-tenant row-level isolation + WAL backups
Auth
Per-tenant accounts, signed sessions, MFA-capable
Audit + ops
Immutable audit log, daily backup drill, replica health probe
Highlights
Strict tenant isolation at the query layer
Row-level filters baked into every read. No application-layer "remember to filter by tenant_id" — the database refuses to return cross-tenant rows. Verified by a deny-list of cross-tenant query patterns in CI.
Long-running ops without dedicated DBAs
Daily backup drills (load dump into throwaway Postgres, count schema_migrations rows for parity), replica health alerting, and a runbook library. Customer ops focuses on their product, not on keeping the platform alive.
