Technical Architecture & Infrastructure

Deep dive into our technical stack, scalability, and performance

Why did you choose PostgreSQL over MySQL or other databases? +

PostgreSQL was selected for several critical reasons:

  • JSON/JSONB Support: Native JSON storage for flexible survey responses without schema rigidity
  • Advanced Indexing: GIN indexes for JSON queries, partial indexes for performance optimization
  • ACID Compliance: Full transactional integrity for audit trails and compliance requirements
  • Extensibility: Custom functions, triggers, and data types for complex analytics
  • Performance: Superior query optimization and parallel processing for large datasets
  • Compliance: Built-in encryption, role-based access, and audit logging capabilities
Technical Implementation: We use JSONB columns for survey responses with GIN indexes, allowing sub-second queries across millions of records. Our custom functions calculate wellness scores in real-time while maintaining referential integrity.
How does your QR code versioning system work technically? +

Our QR versioning system is built on a sophisticated audit trail architecture:

  • Immutable History: Every QR code change creates a new version record with complete metadata
  • Cryptographic Integrity: Each version includes SHA-256 hashes for tamper detection
  • Rollback Capability: One-click reversion to any previous version with full audit trail
  • Change Attribution: Every modification tracked with user, timestamp, and reason
  • URL Generation: Dynamic survey URLs with institution and location parameters (templates assigned per location in database)
Database Schema: The qr_code_versions table includes version_number, qr_code_url, generated_by, change_reason, created_at, and cryptographic signatures. Our API automatically increments versions and maintains referential integrity.
What's your approach to horizontal scaling and load balancing? +

Our scaling strategy is designed for enterprise-grade performance:

  • Stateless Architecture: All application state stored in database, enabling unlimited horizontal scaling
  • Database Read Replicas: Analytics queries distributed across read-only replicas
  • CDN Integration: Static assets and QR codes served via global CDN
  • Redis Caching: Session storage and frequently accessed data cached in Redis
  • Connection Pooling: PgBouncer for efficient database connection management
  • Microservices Ready: API-first design enables service decomposition as needed
Performance Metrics: Our architecture supports 10,000+ concurrent users with sub-100ms response times. Database queries are optimized with composite indexes and query plan analysis.

Security & Compliance

FERPA compliance, data protection, and security measures

How do you ensure FERPA compliance when collecting student wellness data? +

FERPA compliance is built into our core architecture through multiple layers:

  • Anonymous Collection: No personal identifiers (name, SSN, student ID) ever collected or stored
  • IP Address Hashing: All IP addresses hashed with SHA-256 before storage
  • No Session Tracking: Survey responses cannot be linked to individual students
  • Data Minimization: Only wellness metrics collected, no academic or personal information
  • Institution Isolation: Complete data segregation between institutions
  • Audit Trails: All data access logged for compliance monitoring
Legal Framework: Our system operates under FERPA's "directory information" exception and "legitimate educational interest" provisions. We provide legal documentation for institutional review.
What encryption and security measures protect the data? +

Multi-layered security approach protecting data at rest and in transit:

  • Transport Security: TLS 1.3 encryption for all data transmission
  • Database Encryption: AES-256 encryption at rest with key rotation
  • Password Security: bcrypt hashing with salt rounds (cost factor 12)
  • Session Security: Secure, HTTP-only cookies with CSRF protection
  • Input Validation: SQL injection prevention with prepared statements
  • Rate Limiting: DDoS protection and abuse prevention
Security Headers: HSTS, CSP, X-Frame-Options, and X-Content-Type-Options headers implemented. Regular security audits and penetration testing conducted.
How do you handle data retention and deletion requests? +

Comprehensive data lifecycle management with automated compliance:

  • Configurable Retention: Institution-specific retention policies (default 7 years)
  • Automated Deletion: Scheduled cleanup of expired data with audit logs
  • Right to Erasure: Complete data removal capabilities (though data is already anonymous)
  • Backup Security: Encrypted backups with separate key management
  • Compliance Reporting: Automated generation of data handling reports
Privacy by Design: Since we don't collect personal identifiers, "deletion" requests are handled through data aggregation and anonymization rather than individual record removal.

Competitive Advantages & Market Position

Why WellPulse is the superior choice for campus wellness monitoring

What's your competitive moat? Why can't competitors easily replicate this? +

Our competitive moat is built on several defensible advantages:

  • FERPA Compliance Expertise: Deep understanding of educational privacy laws and implementation
  • QR Versioning System: Proprietary audit trail technology with rollback capabilities
  • Institution-Specific Customization: Multi-tenant architecture with domain-based routing
  • Real-time Analytics Engine: Custom wellness scoring algorithms and trend analysis
  • Integration Ecosystem: APIs for SIS, LMS, and campus management systems
  • Compliance Documentation: Pre-built legal frameworks for institutional adoption
Technical Barriers: Our JSONB-based analytics engine with custom PostgreSQL functions would take competitors 12-18 months to replicate. The QR versioning system with cryptographic integrity is proprietary technology.
How do you compare to existing campus wellness solutions like Qualtrics or SurveyMonkey? +

WellPulse offers distinct advantages over generic survey platforms:

  • QR Code Integration: Physical campus deployment with version control
  • Cost Efficiency: No per-response pricing - unlimited surveys included
  • Educational Focus: Built for student affairs, not market research
Key Differentiator: While Qualtrics charges per response and requires extensive privacy configuration, WellPulse is anonymous by design and includes unlimited responses in institutional pricing.
What's your pricing model and how does it scale with institution size? +

Transparent, scalable pricing designed for educational institutions:

  • Institution-Based Pricing: Flat annual fee per institution, not per student or response
