Securing 1.3 Billion Documents with a Legally Certified Digital Archive
Building a national platform to store, search, and govern financial records at scale.
Context
The Romanian Ministry of Finance oversees budget execution, tax systems, and government financial operations. Its archive spans decades of critical documentation – from procurement contracts to fiscal reports – and must meet strict national standards for accessibility, retention, and legal compliance.
Problem
The ministry’s digital archive had evolved into a patchwork of disconnected systems. Staff struggled to find records, especially across departments, and audit readiness was slow and inconsistent.
- Legacy tools couldn’t support documents with electronic signatures or legal timestamps.
- Role-based security was crude or missing, exposing sensitive data to overpermissioned users.
- Adding a new document type (e.g., for a policy change) required custom development and weeks of work.
- Archive performance was poor, often requiring minutes to load files under load.
Solution
Preux delivered the archive UI and platform strategy in collaboration with local engineering teams. The result was a certified, performant national archive.
- Designed a single, extensible schema to support existing and future document types.
- Implemented search and indexing tools that retrieve thousands of documents per second.
- Enabled e-signature support and immutable audit trails to meet national archiving laws.
- Built tools for admins to configure new document formats without dev input.
- Applied role-based security mapping to 30,000+ employees with granular policies by department, document type, and clearance level.
Outcome
Docs indexed and stored
The new platform consolidated billions of files under a single certified system.
Peak document retrieval speed
High-throughput architecture enables real-time access at national scale.
Users across all departments
Granular access policies ensure each user sees only what they’re cleared to view.
New document type deployment
What once took weeks is now faster taking only a few clicks via config tools.
The Ministry now operates on a single, compliant platform where records are secure, discoverable, and scalable. Staff across agencies retrieve what they need instantly, auditors can access compliant files without bottlenecks, and the archive continues to expand as new formats emerge. The platform has become a model for digital governance in Romania and beyond.
