HDS-compliant e-health apps ready for complex patient journeys

Multi-tenancy (strict data isolation between clients), complex billing (plans, add-ons, prorata, upgrades), SSO and granular permissions, stable and versioned public APIs.

Each of these is addressed seriously from scoping, not improvised along the way.

We pick the isolation model that fits your context: shared schema, schema per tenant or database per tenant. Each approach has trade-offs on cost, performance and isolation.

For most early-stage B2B SaaS, shared schema with properly configured row-level security is the right balance.

One to two week sprints, continuous production releases, feature flags to test with select customers before general rollout.

The product team keeps a sustainable pace and your first customers see added value every sprint.

We work with HDS-certified hosts (OVH Healthcare, Scaleway Healthcare, AWS HDS). The choice depends on your volumes, ecosystem and sovereignty sensitivity.

We structure the architecture to respect HDS requirements (logging, encryption, separation) by design, not as a patch.

Yes, we integrate HL7 FHIR for inter-SIH exchanges, DMP for patient record access, and APIs from common vendors (Doctolib, Maincare, etc.).

Interoperability is a complex topic requiring serious scoping: we guide you on what's realistic and what costs a lot for little value.

End-to-end encryption, strict multi-facility partitioning, granular consent management, pseudonymization for analytics, comprehensive access logging.

Rules are not decorative: they are tested regularly through external security audits.
