- Protecting patient data and privacy in every layer
- Connecting to EHRs, labs, devices and third-party services
- Setting standards for code quality, testing and releases
- Working with clinicians, designers, compliance and product teams
- Coaching developers and managing delivery and risk

Healthtech-Specific Considerations
- Protected health information (PHI): apply minimum necessary access, encryption and audit logging.
- Vendor agreements: use a business associate agreement (BAA) or equivalent contract with any vendor that handles PHI.
- Consent and data residency: track what users agreed to and where data may be stored.
- Medical device software: software used for diagnosis or treatment decisions may be regulated, for example under IEC 62304 and FDA or EU rules.
- Clinician usability: avoid alert fatigue and keep common tasks fast.
Front-End Tools
| Tool | Typical use |
|---|---|
| React | Component-based interfaces for web apps |
| Next.js | React framework with server rendering and routing |
| TypeScript | Typed JavaScript that catches errors early |
| React Native | Cross-platform mobile apps |
| Storybook | Building and reviewing UI components in isolation |
Back-End and API Tools
| Tool | Typical use |
|---|---|
| Node.js with NestJS | Structured TypeScript services and APIs |
| Spring Boot | Enterprise Java services, common with HAPI FHIR |
| FastAPI | Fast Python APIs with automatic documentation |
| Django | Full-featured Python web framework |
| ASP.NET Core | C# services for Microsoft-based stacks |
| OpenAPI | Standard way to describe and document REST APIs |
Data and Storage Tools
- PostgreSQL: reliable relational database with strong features and JSON support.
- MongoDB: document database for flexible data shapes.
- Redis: caching and session storage.
- OpenSearch or Elasticsearch: full-text search across records and documents.
- S3-compatible object storage: encrypted storage for files and images.
- Kafka: event streaming between services and integrations.
Health Data Standards and Integration
| Tool or standard | Typical use |
|---|---|
| HL7 FHIR | Modern API standard for exchanging health data |
| SMART on FHIR | Launching and authorising apps connected to EHRs |
| HAPI FHIR | Open-source Java FHIR libraries and server |
| Medplum | Open-source FHIR-based platform for health apps |
| HL7 v2 | Older message standard still common in hospitals |
| SNOMED CT | Clinical terminology for conditions and procedures |
| LOINC | Codes for lab tests and observations |
Use vendor sandboxes and synthetic data for development. Never copy real patient data into test systems.
Authentication and Identity
- OAuth 2.0 and OpenID Connect: standard authorisation and sign-in.
- Keycloak: open-source identity and access management.
- Auth0 and Amazon Cognito: managed identity services.
- WebAuthn: passkey and hardware key sign-in standard.
Plan role-based access, session timeouts and multi-factor authentication for clinical and administrative users.
Cloud and Infrastructure
| Tool | Typical use |
|---|---|
| AWS | Cloud services, including healthcare-oriented offerings |
| Microsoft Azure | Cloud platform with health data services |
| Google Cloud | Cloud platform with a Healthcare API |
| Docker | Packaging applications consistently |
| Kubernetes | Running and scaling containers |
| Terraform | Infrastructure defined as code |
Use only services covered by your BAA or equivalent agreement when handling PHI.
CI/CD and Testing
| Tool | Typical use |
|---|---|
| GitHub Actions | Automated builds, tests and deployments |
| GitLab CI | Pipelines integrated with GitLab repositories |
| Jest | Unit tests for JavaScript and TypeScript |
| Playwright | End-to-end browser testing |
| Cypress | Front-end and end-to-end testing |
| SonarQube | Code quality and security checks |
Security and Compliance
| Item | Purpose |
|---|---|
| HIPAA | US privacy and security rules for protected health information |
| GDPR | EU data protection law covering personal and health data |
| SOC 2 | Audit report on security and related controls |
| HITRUST | Certifiable security framework used in healthcare |
| OWASP ASVS | Checklist for verifying application security |
| Dependabot | Automated alerts and updates for vulnerable dependencies |
Observability
- Sentry: error tracking for web and mobile apps.
- Datadog: monitoring, logs and traces in one platform.
- Prometheus and Grafana: open-source metrics and dashboards.
- OpenTelemetry: standard for collecting traces, metrics and logs.
- PagerDuty: on-call alerting and incident response.
- Log hygiene: keep PHI out of logs and error messages.
Accessibility and Design
- WCAG 2.2: guidelines for accessible web content.
- axe DevTools and Lighthouse: automated accessibility checks.
- Figma: design and prototype collaboration with clinicians and product teams.
Leadership and Collaboration
- Jira and GitHub Projects: planning and tracking work.
- Confluence: shared documentation and decisions.
- Architecture decision records (ADRs): short notes explaining why key choices were made.
- DORA metrics: deployment frequency, lead time for changes, change failure rate and time to restore service.
Step-by-Step Workflow
- Clarify goals and regulation. Define clinical and business outcomes, users and whether the software could count as a regulated medical device.
- Design architecture and data model. Map PHI boundaries, choose FHIR resources, plan multi-tenancy, audit logs and failure handling.
- Set up secure foundations. Configure identity, secrets management, environments, infrastructure as code, vendor agreements and PHI-free logging.
- Build vertical slices. Deliver small end-to-end features through front end, API and database, with a shared design system and accessibility checks.
- Integrate with health systems. Connect through FHIR and SMART on FHIR, test in sandboxes with synthetic data and handle vendor differences.
- Test, secure and validate. Run unit, end-to-end, security, accessibility and load tests, and have clinicians review safety-critical flows.
- Release, monitor and iterate. Use feature flags and staged rollouts, watch metrics and errors, run incident reviews and track DORA metrics.

Checklist and Common Mistakes
- Privacy: is PHI encrypted, minimised and absent from logs?
- Integration: are EHR differences handled and tested?
- Quality: do automated checks run on every change?
- People: have clinicians tested the real workflow?
Frequently Asked Questions
1. What does a Full-Stack Healthtech Developer Lead do?
They guide design and delivery of health software across front end, back end, data and infrastructure, while ensuring security, privacy, interoperability and good engineering practice.
2. Which tech stack is best for healthtech?
There is no single best stack. Common choices include React with TypeScript, Node.js, Java or Python back ends, PostgreSQL and a major cloud provider, chosen for team skills and compliance needs.
3. Why is FHIR important?
FHIR is a widely used standard for exchanging health data through web APIs. It helps applications connect to EHRs and other systems more consistently.
4. How do I keep PHI safe in development?
Use synthetic or properly de-identified data, limit access, encrypt data, keep PHI out of logs and use environments covered by appropriate agreements.
5. When does health software count as a medical device?
It depends on its intended use and the local rules. Software that supports diagnosis or treatment decisions may be regulated, so seek regulatory advice early.
Conclusion
A strong healthtech stack combines modern web tools, open health standards, careful security and steady delivery practices, guided by input from clinicians. Protect patient data in every layer, test with synthetic data and measure delivery health. Always confirm current tool details, regulations and vendor terms in official sources.
