The goal

RYVIA 3D was designed as a working custom 3D-printing service rather than a demo page. A customer needs to register, verify email, upload photos and 3D models, receive a quote, talk to the seller and follow order status.

Architecture

The project uses a Node.js backend, PostgreSQL and private file storage. The interface works as a single application with a customer dashboard and an administrative area.

  • Render — backend runtime;
  • Neon PostgreSQL — database;
  • Cloudflare R2 — private order files;
  • ClamAV — upload scanning;
  • Resend — verification and password-reset email.

Security and file handling

Order files could not simply live in a public directory. The project uses private storage, server-side file validation and antivirus scanning. MFA protects administrative access.

A production project has to handle more than the happy path: unavailable storage, invalid files, failed email delivery and incomplete uploads all need predictable behaviour.

The final stage

After functional testing, the project received mobile polish, an HTTPS domain, production email delivery and SEO setup. Registration, file-backed orders, the customer account and the administrator flow were tested separately.

What this case demonstrates

RYVIA 3D became a useful KAMERTON example of a project where frontend work is only one part of the job. A real web service also needs data, storage, security, integrations, deployment and testing.
