Building a healthcare app with NestJS? Let us review it.
Expert code review for healthcare apps built with NestJS. We fix NestJS-specific security gaps, optimize performance, and handle deployment. From $19.
Common NestJS issues we find
Real problems from NestJS codebases we've reviewed.
Missing authentication guards
Controllers and routes without @UseGuards decorators, leaving endpoints publicly accessible without any auth checks.
Incorrect dependency injection scope
Services registered with wrong scope (default singleton vs request-scoped) causing shared state between requests and data leakage between users.
Unvalidated DTOs
Data Transfer Objects without class-validator decorators or missing the global ValidationPipe, accepting any shape of input data.
Circular dependency issues
Modules importing each other in cycles, causing runtime errors or undefined injections that only surface in production.
Healthcare App challenges to solve
Key healthcare app concerns that AI-generated code often misses.
HIPAA-compliant data handling
Protected health information must be encrypted at rest, encrypted in transit, access-logged, and stored only in HIPAA-compliant infrastructure. AI tools store data in standard databases with no encryption, no access logging, and on hosting providers that may not offer HIPAA-compliant tiers.
Access controls and minimum necessary rule
Healthcare regulations require that users only access the minimum data necessary for their role. A nurse sees different data than a billing clerk. AI-generated auth gives everyone the same access level, which violates the minimum necessary principle.
Audit logging for compliance
Every access to patient data must be logged — who viewed it, when, from where, and what they accessed. These logs must be tamper-proof and retained for six years. AI tools don't generate any audit logging, let alone compliant audit trails.
Telemedicine reliability
Video consultations, real-time messaging, and appointment scheduling must work reliably — a dropped video call during a medical consultation is not just frustrating, it's a patient safety issue. AI tools generate basic WebRTC setup without fallback mechanisms or connection quality monitoring.
What we check
Key areas we review for NestJS healthcare app projects.
Data encryption — PHI encrypted at rest and in transit
Access controls — role-based access with minimum necessary enforcement
Audit logging — tamper-proof logs of all PHI access
Infrastructure — HIPAA-eligible hosting and database configuration
Not sure if your app passes? Our code audit ($19) checks all of these and more.

Frequently asked questions
Can you review a healthcare app built with NestJS?
Yes. We regularly audit NestJS healthcare app projects and understand the specific patterns and pitfalls of this combination. Our review covers security, performance, and deployment readiness.
What issues do you find in NestJS healthcare apps?
Common issues include missing authentication guards and incorrect dependency injection scope on the NestJS side, combined with healthcare app-specific concerns like hipaa-compliant data handling and access controls and minimum necessary rule. We check for all of these and more.
How do I make my NestJS healthcare app production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For NestJS healthcare app projects, the typical path is: fix security gaps, address healthcare app-specific requirements, optimize NestJS performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a NestJS healthcare app?
Our code audit delivers a full report within 24 hours. For NestJS healthcare app projects, we check security, architecture, performance, and deployment readiness across all NestJS-specific patterns. Fixes are scoped separately with a fixed quote.
