Zartras — Software Engineers — NL

Built to deliver.

Every system worth building moves something: files to a client, a session to a paid invoice, a message across an enterprise backbone. Zartras designs, builds and runs that delivery layer — reliably, verifiably, every time.

Software-as-a-service, designed, built and operated by Zartras end to end.

You ──────▶ Your client

FileLobby

Client file delivery, done properly. Your clients deserve better than email attachments — FileLobby is the delivery layer between you and them. Every file, every version, every handoff: organised and on the record.

  • Multi-tenant with bring-your-own storage and per-tenant branding
  • Versioned handoffs — stacked versions of a file, with full audit trail
  • Granular permissions, down to upload-only drop-boxes for external parties
In production

Session ──────▶ Paid invoice

TherapieFactuur

Invoicing for Dutch therapy practices — from session to paid invoice in four steps. PDF invoices, iDEAL payments, automatic reminders. Built for a domain where privacy is not optional.

  • Client data encrypted at rest — AES-256-GCM envelope encryption, per-record keys
  • Fail-closed tenant isolation, enforced at the database access layer
  • iDEAL payments via Mollie, with idempotent webhook handling

For a global healthcare enterprise, Zartras builds and maintains the systems that move more than 100,000 files and messages a day between thousands of trading partners — from the admin consoles down to the webMethods packages and Java that do the moving.

Managed file transfer platform

An enterprise managed-file-transfer mailbox platform, built full-stack: the admin console for trading partners, transfers, documents and statistics — and the webMethods packages beneath it, covering SFTP and SMB connectivity, encryption and mail delivery in flow services and Java, each with its own test package.
