Web Apps & Backend Systems
System Software for Connected Device Ecosystems
We build web applications, device management platforms, and backend systems for connected medical, digital health, and consumer devices.

Web Apps & Backend in connected systems
Backend Systems Control What Happens in the Field.
Web applications give users visibility and control over device ecosystems. Backend systems make that control reliable at scale. Built without backend coordination, device features promise what infrastructure can’t deliver, and systems fail in production.
We build web and backend systems with device-level awareness. Because we work across firmware, mobile, cloud, and web, we design for what the connected system can reliably support.
The Result: Web applications and backend infrastructure that integrate cleanly with your device ecosystem, handle production scale, and enable reliable control.

What we solve for
Web Apps & Backend Development at Every Stage
Whether building from scratch, validating approaches, or resolving production issues, we bring the backend systems depth you need.

Backend Codebase
Tested, documented services with CI/CD pipelines, deployment automation, and configuration management.
API Documentation
Versioned endpoint specifications, API contracts, authentication flows, request/response examples, and error handling guidance.
Security Implementation
Authentication, authorization, encryption at rest and in transit, and comprehensive audit logging.
Testing Suite
Automated unit, integration, and load tests covering APIs, data flows, and third-party integrations.
Deployment & Monitoring
Infrastructure as code, observability dashboards, alerting configurations, and operational runbooks (with availability documentation for compliance needs).
HOW WE WORK
Backend Development Coordinated Across Your Connected System
We develop web services alongside firmware and mobile teams, maintaining regulatory traceability and production readiness throughout.

Coordinated development
APIs designed alongside firmware and mobile teams.
We develop backend services in parallel with device firmware and mobile apps. API contracts, data models, and sync strategies are defined collaboratively before implementation. This ensures that mobile teams know the data structures, that firmware understands the payload formats, and that authentication flows are agreed upon upfront.
Example in practice: Device authentication flows are architected with firmware constraints and mobile app UX in mind simultaneously, preventing integration rework during system testing.
Traceable architecture
Design decisions linked to requirements and risk controls.
Backend architecture documentation maintains traceability between system requirements, design decisions, and implementation. Security controls map to identified risks. API specifications link to use cases. This documentation supports FDA submissions and certification processes.
Example in practice: Each API endpoint maps to specific system requirements and risk mitigations, with verification evidence already built and ready for regulatory review.


Production readiness
Infrastructure and monitoring were planned from the start.
We architect backend services with production deployment in mind from day one. Load testing validates performance under expected device counts. Monitoring dashboards and alerting are configured during development, not after launch.
Example in practice: Load tests simulate 10,000 concurrent device connections during development, validating performance and identifying bottlenecks before production launch.
See how we work across disciplines.
Connected systems, engineered as one.
