QuaLeadx
A secure, multi-tenant quality management system centralizing critical ISO 9001 workflows.
The product
Engineering clarity
into complexity.
QuaLeadx brings documents, non-conformities, CAPA, risks, audits and performance indicators into a traceable enterprise workspace with strict tenant isolation and secure document handling.
- Tenant-isolated architecture and granular role-based access
- Immutable audit chains for critical operations
- Secure S3-compatible storage with antivirus scanning
- Background notifications, reporting and export workflows
01 / The challenge
The problem behind
the interface.
Quality teams were managing connected ISO 9001 processes across fragmented tools. QuaLeadx centralizes documents, non-conformities, CAPA, risk and audits while preserving strict tenant boundaries and operation traceability.
Project constraints
- Strong multi-tenant isolation
- Immutable evidence for critical operations
- Sensitive file handling
- Long-running reporting and notification jobs
- Granular roles and MFA
02 / Architecture
Clear boundaries.
Purposeful layers.
Experience
React 19 workspace with reusable workflow forms, tables, filters and dashboards.
Domain API
NestJS and Fastify modules organized around quality-management capabilities.
Data and jobs
MongoDB tenant-scoped models, Redis and BullMQ background processing.
Documents
MinIO/S3 storage with ClamAV scanning before files enter trusted workflows.
03 / Engineering decisions
Trade-offs made
explicit.
Tenant context at every data boundary
Isolation is enforced as an architectural rule instead of relying only on interface-level filtering.
Chain audit records
SHA-256-linked audit entries make unauthorized history changes detectable for sensitive quality operations.
Move slow work off the request path
Exports, notifications and reports run through BullMQ to protect interactive response times.
04 / System toolkit
A stack assembled
for the problem.
Every technology earns its place in the architecture. The interactive field represents the system's core building blocks.
