Large Scale PDF Report Generation
Triophore developed a serverless, scalable solution using AWS Lambda for LifeSignals INC to generate large volumes of healthcare PDF reports, improving data presentation and regulatory compliance.
The Challenge
Business Problem
LifeSignals INC needed to generate accurate, comprehensive, and on-demand reports from patient data for clinical decision-making, regulatory compliance, and patient communication, but their existing reporting mechanisms were not scalable enough to handle the on-demand, large-scale generation required.
The Goal
Develop a highly scalable and efficient solution for generating large volumes of PDF reports from patient data on demand.

The Solution
Discovery & Architecture
Triophore proposed and developed a serverless, event-driven architecture to address LifeSignals' challenges. The architecture leveraged AWS Lambda for scalable execution, Nuxt.js for dynamic HTML templating, and Puppeteer for rendering HTML into PDFs. The system was designed with an event-driven trigger mechanism, enabling report generation from various sources. AWS S3 provided secure storage for the reports, and AWS SES handled secure email delivery, completing a secure and scalable system.
Development Phase
The solution utilized Node.js for developing the core logic of AWS Lambda functions. Nuxt.js was used to create highly customizable and dynamic HTML templates for the reports. Puppeteer was used for headless browser rendering of HTML templates into PDFs. AWS Lambda provided the serverless compute service, AWS SES for email delivery and AWS S3 for storage.
Key Feature Implementation
On-demand report generation, Dynamic HTML templating, Headless browser PDF rendering, Secure storage and delivery.
The Results
Performance
The implementation provided high performance in report generation, improving turnaround times for critical patient data.
Scalability
The serverless architecture allowed LifeSignals to generate thousands of reports concurrently on demand, eliminating previous bottlenecks and supporting rapid growth.
User Impact
Improved data presentation with dynamic templating and high-fidelity PDF rendering ensures professional, clear, and accurate presentation of complex patient data.
Business Efficiency
The pay-per-execution model of AWS Lambda significantly reduced operational costs. Automated, on-demand report generation freed up valuable staff time and resources.
