Do you build HIPAA-compliant healthcare apps?

We build to HIPAA-aware controls: encryption at rest with key rotation, audit logging on every PHI read and write, role-based access with least-privilege defaults, automatic session timeouts, and BAA-ready vendor architecture (AWS, Vercel, Postgres providers, email transports). We are not a HIPAA-certifying auditor and we do not stamp the compliance report. What we ship is a codebase your covered entity or business associate can present to a real auditor without flinching.

What kinds of healthcare products have you actually shipped?

A dental patient-financing marketplace that connects practices, patients, and lenders in a single transaction flow. A health tracking platform focused on childhood obesity intervention with provider dashboards and patient mobile apps. Both clients are based in Arizona. Both products are live and being used by real patients today.

Do you do clinical / EHR integration work?

We integrate with EHRs at the API layer (FHIR, HL7 where available, vendor REST APIs for Epic, Cerner, Athena). We do not build EHRs from scratch and we do not implement direct ADT or HL7v2 message brokers without a third-party engine. If your project needs deep EHR integration with PHI flowing both directions, we will pair with a clinical-integration partner rather than pretend it is our core competency.

How long does a healthcare MVP take?

A patient-facing app with auth, profile, one core flow, and basic admin tooling: 10 to 14 weeks. Add provider dashboards: 14 to 20 weeks. Add billing integration or third-party clinical data: 20 to 28 weeks. The biggest schedule risk is not the engineering. It is the legal review of your data flows and BAAs, which is on your side, not ours.

What does a typical healthcare SaaS build cost?

Patient-only mobile or web app with one workflow: $45,000 to $95,000. Patient app plus provider/admin portal: $95,000 to $200,000. Multi-stakeholder platform with billing or external clinical data: $200,000 to $400,000. We give a fixed-price quote when the data-flow map is locked. Time and materials when it is not.

Can you build for regulated specialties (mental health, pediatrics, oncology)?

Yes within reason. Mental health apps need explicit suicide-risk handling and clinician escalation paths; we have built basic versions of these but a clinically-licensed advisor on your side is non-negotiable. Pediatrics requires COPPA controls if you collect data on under-13 users; we have shipped one pediatric-focused platform. Oncology and other high-acuity verticals are out of our depth without a clinical co-founder.

Are you only in Tampa, or do you serve healthcare clients elsewhere?

Tampa-based, Arizona-shipped is the actual pattern so far. Both of our delivered healthcare clients are in Arizona, and the engagements ran remote-first with weekly video syncs, shared documentation, and a single point of contact on each side. We are comfortable serving healthcare clients anywhere in the continental US.

What we build

What we build for healthcare teams

Six healthcare surfaces, each one shipped at least once for a real client. Each has a clinical-workflow, regulatory, and operator-tooling shape worth knowing before you scope.

Care in their pocket.

Onboarding, secure messaging, appointment booking, push reminders, accessibility-first interaction. Our childhood-obesity platform put a patient app in front of families managing daily care.

The operator surface, first-class.

Patient lists, treatment tracking, clinical notes when in scope, exception queues, role-based views per clinician. We build the provider side as a real product, not an afterthought.

//vitals.sync

Signal out of the noise.

Manual entry, device sync (HealthKit, Google Fit, Fitbit), trend dashboards, and intervention triggers when metrics drift. We instrument the data honestly.

Encryption at rest

Audit log on PHI

BAA-ready vendors

Built in, not bolted on.

Encryption at rest with rotation, audit logging on PHI access, least-privilege IAM, session timeouts, BAA-ready vendors. Designed in from week one, not patched before an audit.

//ehr.fhir

FHIRAPIEHR

Honest at the integration edge.

API-layer integration with major EHRs (FHIR, vendor REST). We pair with a clinical-integration partner for direct HL7v2 or deep ADT work, and say where our depth ends.

Two healthcare products we shipped

Both clients are Arizona-based. Both products are live with real patients today. One is a financing marketplace bridging dental practices, patients, and lenders. One is a childhood-obesity tracking platform with provider dashboards and a patient mobile app.
