Clinical software I've built and shipped.
I'm Selvadinesh, a healthcare technology builder. I work across AI clinical documentation, FHIR and HL7 interoperability, and SMART on FHIR EHR integration, and I care about software that runs in front of real clinicians, not slideware.

FHIR, SMART on FHIR, HL7v2, and the Swiss EPR (EPD).
Open to healthcare-IT roles in Switzerland.
Standards coverage
Each capability here is backed by a project that proves it.
| Capability | Proven by |
|---|---|
| FHIR profile conformance (US Core) | OpenTrace |
| CDS Hooks clinical decision support | OpenTrace |
| SMART App Launch + OAuth2/PKCE on Epic | PatientLens |
| EHR launch on Cerner | VitalScope |
| Clinical scoring logic (NEWS2) | VitalScope |
| HL7v2 messaging in production | Arvi Health |
| Multi-tenant clinical SaaS + compliance | Arvi Health |
Built against US sandboxes and US Core; I'm currently extending the same standards work into CH Core and the Swiss EPR (EPD).
Featured work: four healthcare projects
Arvi Health
production AI clinical documentation · Lead software developer at Hype Insight · live with clinics in Australia
Arvi Health is a product built at Hype Insight, where I work as lead software developer, serving medical clinics in Australia. It turns clinician inputs into structured notes and letters through an LLM pipeline, built to meet Australian privacy and data-residency requirements. As lead software developer I drive its engineering and day-to-day operation, working within the team that ships and runs it: the documentation pipeline, HL7v2 messaging via HealthLink, multi-tenant architecture, audit logging, and subscription billing. It is the clearest evidence on this site that I help build and operate real clinical software in production, not demos.
OpenTrace
FHIR clinical tooling, CDS Hooks · 2nd place, Medblocks FHIR App Challenge
A clinical tool built on US Core profiles with CDS Hooks for decision support, and LLM reasoning to surface unclosed diagnostic loops. It placed 2nd in the Medblocks FHIR App Challenge, which is third-party validation of the standards work. CDS Hooks is a capability most candidates can’t show.
PatientLens
SMART on FHIR on Epic · Native Android · published v0.1.0
A patient-facing native Android app that authenticates against Epic via SMART App Launch with OAuth2/PKCE. This is the hard part of EHR integration done properly: the auth and launch flow, not just reading a resource. Published as a v0.1.0 APK.
VitalScope
EHR launch on Cerner, NEWS2 scoring · Practitioner-facing · SMART on FHIR
A Cerner EHR-launch app that reads live vitals and computes NEWS2 early-warning scores. Paired with PatientLens, it shows EHR integration across two vendors (Epic and Cerner), and the NEWS2 logic shows correct clinical calculation, not just data plumbing. Runs in the Cerner sandbox, so there’s no public URL by design.
About
About
I started in web and UI/UX design and moved through into engineering and product, which is why I work comfortably from user research and interface design all the way to a deployed, operating system. For the last stretch my focus has been healthcare: building and running Arvi Health, and deepening interoperability through FHIR, SMART on FHIR, HL7, and SNOMED CT.
The way I work is product-first. I direct and assemble systems quickly, ship them, listen to the people using them, and improve. I care more about software that runs in front of real clinicians than about clever code nobody uses.
I'm based in Thurgau, Switzerland on a Swiss B permit, looking for healthcare-IT work where shipped products and domain understanding count. German B2 and improving; English professional; Tamil native.
My focus now is bringing this into the Swiss environment: CH Core, HL7 CH, the EPD (elektronisches Patientendossier), and Swiss hospital information systems and ICT.
