Patient apps
Onboarding, profile, secure messaging, appointment booking, push notifications, accessibility-first interaction. Our childhood-obesity tracking platform put a patient mobile app in front of families managing daily care plans.
Industry pillar
Healthcare software development partner. Two production products live with Arizona-based clients.
We build patient apps, provider dashboards, and HIPAA-aware architecture for digital health founders and clinical product teams. Patient financing. Health tracking. Care coordination. Tampa-based agency, Arizona-shipped track record.

The short version
Healthcare software fails for two reasons: the clinical workflow was misunderstood, or the data architecture was bolted on before the audit. We have shipped two healthcare products that survived both. The sections below are what we learned and what we say no to.
What we build for healthcare teams
Six healthcare surfaces, each one shipped at least once for a real client.
Provider dashboards
Patient lists, treatment tracking, clinical notes (when in scope), exception queues, role-based views per clinician role. We build the operator surface as a first-class concern, not an afterthought.
Health tracking + wearables
Manual entry, device sync (Apple HealthKit, Google Fit, Fitbit API), trend dashboards, intervention triggers when metrics drift. The hard part is making sense of the noise; we instrument it honestly.
Patient financing + billing
Marketplace connections between practices, patients, and lenders. Stripe Connect for patient-pay flows. Our dental-financing platform handles end-to-end transaction flow with KYC for both sides.
HIPAA-aware architecture
Encryption at rest with rotation, audit logging on PHI access, least-privilege IAM, session timeouts, BAA-ready vendors. We design this in from week one, not patched on before an audit.
EHR + clinical data integration
API-layer integration with major EHRs (FHIR, vendor REST). We pair with a clinical-integration partner for direct HL7v2 or deep ADT work. Honest about where our depth ends.
Why DesignKey for healthcare
What we believe about building healthcare software the right way
01
Two production healthcare products, both live
Dental patient financing and childhood-obesity health tracking. Both Arizona-based clients. Both products are used by real patients today, not stuck in pilot purgatory.
02
We build HIPAA-aware from day one
Encryption, audit logs, BAA-ready vendors, role-based access. Not because we get audited; because the alternative is rebuilding before your first enterprise customer.
03
We know where our depth ends
We have not shipped a system that brokers HL7v2 messages directly. We have not built an EHR. We have not been the technical owner of a Class II medical device. When your project needs those, we will tell you on the discovery call instead of inventing capability.
04
Senior engineers only on patient-facing code
A bug in a payment platform costs money. A bug in a patient app can affect care. We staff healthcare work with engineers who have shipped a regulated product before, not junior hires learning on your data.
05
Tampa rates for US-time-zone delivery
Roughly 30 to 40 percent below Boston or Bay Area healthtech specialists for equivalent senior engineering, with full overlap with the continental US working day.
06
We design the provider surface, not just the patient app
Most healthcare MVPs ship a beautiful patient app and a Google Form for the clinic. We build the provider dashboard as a real product in the same engagement because the clinic-side adoption is what determines whether the patient app gets used at all.
Case studies
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.
How a healthcare engagement starts with us
Three steps before code. Skip them and the audit will find what you missed.
- 1
PHI data-flow map
Every place protected health information enters, moves through, lands at rest, and gets surfaced. Every external vendor that touches it. This map is the foundation of the BAA list, the audit log scope, and the encryption boundary. Two-hour session, we facilitate, your clinical or compliance lead validates.
- 2
Clinical workflow walkthrough
The patient journey AND the provider journey. Who logs in, when, on what device, how the data they enter or read fits into the actual care delivery. Most healthcare MVPs fail here. We refuse to scope an engagement without this session because the engineering downstream is unrecoverable if the workflow is wrong.
- 3
Operator + escalation surface spec
The provider dashboard, the exception queue, the "this patient hit a threshold" alert path. We design these in the same engagement as the patient surface because clinic adoption is what determines whether the patient app gets used at all.
