Engineering for
Healthtech.
Healthtech is the sector where the engineering posture is the product. SDEN engineers it from the threat model out, and stays accountable through delivery and the support window after launch.
What we engineer
Healthtech engineering is harder than most teams admit out loud. The data is uniquely sensitive (PHI under HIPAA where it applies, PHI under PHIPA / PIPEDA in Canada), the operational context is unforgiving (a clinician will not work around a slow interface), and the regulatory landscape is plural (HIPAA, PIPEDA + provincial health-privacy law, FDA / SaMD rules for medical devices, the local health-data regulations on top). The engineering shortcuts that other sectors absorb as technical debt show up here as patient safety risk.
SDEN's engineering posture meets this bar. Encryption is end-to-end (TLS 1.3 in transit, AES-256 at rest with KMS-managed keys, customer-managed keys available where the threat model requires it). Tenant isolation is enforced at the type level and the row level. Regional hosting (US, Canada, or EU) is the default. The audit trail is tamper-evident and retained on the cadence the regulator expects.
Clinical workflows, patient portals, telemedicine: engineered for the people who actually use them
Healthtech engineering at SDEN covers the operational surface a clinical team actually touches: patient management with structured clinical records, appointment booking with the routing rules clinics need (specialty, insurance, urgency), patient portals isolated by tenant and audited at every read, telemedicine with end-to-end-encrypted video, and the integrations with the practice management systems, lab providers, and insurance back-ends the clinic already runs.
We design for clinicians, not for screenshots. WCAG 2.2 AA accessibility is the default: the same interface has to work for a clinician at 7 a.m. on minimal sleep and for a patient on a low-end phone in a waiting room. Latency budgets are documented and tested; an interface that takes three seconds to respond loses to paper records, and paper records lose to patient outcomes.
HIPAA + clinical posture from launch, not as a remediation roadmap
Healthtech teams that ship with SDEN do not spend the year after launch fixing the posture for a regulator's inspection. The posture is in the architecture from day one: data minimization at the schema, role-based access at the API, audit trails at the database, regional hosting (US, Canada, or EU) at the infrastructure. The documentation a privacy officer or a hospital's information security team will ask for is in the repository, not on a future-quarter roadmap.
What we will not pretend: SDEN is not a regulatory clearance authority and not a clinical regulatory consultancy. For medical-device software that requires FDA clearance (510(k) / De Novo) or its Health Canada equivalent, the QMS (ISO 13485) and the conformity assessment stay with your team or your regulatory partner. We deliver the engineering that supports them.
The constraints specific to healthtech
Special-category data minimization at the schema
Clinical data is collected only where it has a defined purpose, retained on a documented schedule, and deleted on request under applicable deletion rights (CCPA/CPRA, PIPEDA, GDPR Article 17 where it applies). Erasure is engineered, not promised.
Audit logs on every clinical read
Who read which record, when, from which session: logged and tamper-evident. The bar a hospital's information security team will check before they integrate.
Telemedicine end-to-end encryption
Video and chat for clinical consults run end-to-end-encrypted by default. Recording is opt-in, consent-logged, and stored under the same encryption as the clinical record.
Reversible AI with a clinician in the loop
Every AI-assisted clinical decision has a clinician checkpoint at the moment accountability shifts. The model is decision support, not the decision.
Domains a healthtech engagement leans on
Every SDEN engagement spans multiple domains. These are the ones that ship most of the work in this vertical.
Software & mobile development
SDEN designs and ships production web platforms, SaaS applications, and native and cross-platform mobile apps, from a blank page to App Store, Play Store, and live production.
Cybersecurity
SDEN treats cybersecurity as an engineering discipline applied to every line of code, from threat modeling at the design stage to continuous monitoring once the product is live.
AI & machine learning
SDEN audits the AI integrations a business already runs, designs the custom workflows it should run next, and ships them to production with the evaluation harnesses that keep them honest: RAG, agents, classification, generation.
