Task

Backend Rewrite, Database Migration, Cloud Architecture, AWS Deployment, Multi-Tenant Design, API Integration, DevOps Management

Complete cloud migration and modernization project transforming a legacy desktop ultrasound reporting application into a fully cloud-based, multi-tenant SaaS platform.

The comprehensive transformation involved complete backend rewrite using Express/Node.js with PostgreSQL database, replacing the original SQLite-based desktop architecture while preserving the Angular frontend with updated cloud integration.

Rugas Technologies managed end-to-end cloud deployment on AWS infrastructure including ECS, CloudFront, RDS, and complete production go-live operations.

Problems

The existing desktop application built on SQLite database presented significant scalability limitations and could not support multiple customers or cloud-based operations.

Users were restricted to local installations requiring manual updates, data backups, and lacked the flexibility of remote access from multiple devices or locations.

The architecture could not support modern SaaS business models with multi-tenancy, centralized management, automatic updates, or subscription-based pricing.

Solutions

Complete Backend Rewrite - Rebuilt entire backend using Express and Node.js for cloud-native architecture

Database Migration - Migrated from SQLite to PostgreSQL with AWS RDS for enterprise-grade reliability

Multi-Tenant Architecture - Designed and implemented secure multi-tenant data isolation and access control

Frontend Integration Update - Modified Angular frontend integration layer for cloud API connectivity

AWS ECS Deployment - Containerized application deployed on AWS Elastic Container Service

CloudFront CDN - Implemented global content delivery network for optimal performance

Scalable Infrastructure - Auto-scaling capabilities to handle variable workloads efficiently

Automated Backups - Scheduled RDS backups and disaster recovery mechanisms

Security Implementation - End-to-end encryption, secure authentication, and compliance measures

Production Go-Live Management - Complete deployment coordination and post-launch support

Process

Our transformation approach focused on minimizing disruption while completely modernizing the application architecture for cloud scalability and multi-tenancy.

We executed a phased migration strategy ensuring data integrity, maintaining frontend familiarity, and delivering robust cloud infrastructure.

01

Architecture Design & Backend Development

Analyzed existing desktop application and designed cloud-native architecture with multi-tenant capabilities.

Rebuilt complete backend using Express/Node.js with PostgreSQL, implementing RESTful APIs for frontend integration.

02

Cloud Infrastructure & Deployment

Set up comprehensive AWS infrastructure including ECS for container orchestration, RDS for database, and CloudFront for content delivery.

Containerized application, configured auto-scaling, implemented security groups, and established CI/CD pipelines.

03

Migration, Testing & Go-Live

Migrated existing data from SQLite to PostgreSQL with validation and integrity checks.

Conducted extensive testing including performance, security, and multi-tenant isolation before coordinating production go-live and user onboarding.

Results

Successfully transformed Emrald Ultrasound Reporting from a desktop application into a modern cloud-based SaaS platform, enabling EMRx Technologies to scale their business and serve multiple customers simultaneously.

The multi-tenant architecture eliminated installation complexities, enabled remote access from anywhere, and provided automatic updates and centralized management capabilities.

AWS cloud infrastructure delivered enterprise-grade reliability, security, and performance with 99.9% uptime, while reducing operational costs and enabling rapid feature deployment and customer onboarding.
