The journey
From challenge to results.
Challenges

- Enterprise customers demanding strict access control and data isolation.
Goals
- One secure source of truth for every agreement.
- A clear, trackable workflow from first draft to signature and renewal.
- Proactive tracking of obligations, deadlines and payments.
- An AI-ready foundation for search, review and drafting.
Actions
- Designed a multi-tenant architecture for organisations, business units, departments and teams.
- Built a .NET 8 clean-architecture API on PostgreSQL with a React 18 single-page app.
- Added a Python FastAPI AI service for automatic document text extraction.
- Implemented permission-based RBAC and secure cloud storage with signed URLs.
- Shipped with automated tests and Docker-based deployment for repeatable releases.
Results
- A complete CLM platform covering contracts, obligations and receivables.
- Real-time visibility across 11 contract workflow stages.
