Personalized medicine software on AWS: 60% decrease in post-release bugs

Innowise engineered a serverless infrastructure on AWS, enabling health recommendations for personalized medicine software and implementing a robust CI/CD pipeline for seamless deployment and testing.


Healthcare IT
Client since

Our client is an innovator in the healthcare technology space. They focus on helping individuals with chronic conditions to achieve better health through following tailored AI-driven recommendations. With an emphasis on individualization, the client offers personalized medicine software and a mHealth app for individuals and healthcare providers.

Detailed information about the client cannot be disclosed under the provisions of the NDA.


Redesigning the personalized medicine software to build a robust infrastructure for health recommendations

Our collaboration with the client, initiated in 2022, centered around enhancing their health management system available on web and mobile platforms. Utilizing AI and emotional intelligence (EI) technology, the personalized medicine software dynamically tailors itself to each user’s unique personality, habits, and lifestyle. This approach aims to facilitate sustainable lifelong changes and encourage adherence to treatment programs.The client’s challenge was redesigning a system to track user actions and deliver health-optimizing recommendations more precisely. It required a robust infrastructure for handling recommendations and notifications, which had to be scalable and maintainable. Furthermore, both web and mobile platform versions were lacking comprehensive QA services.


Personalized medicine software with improved back-end system, A/B testing, and streamlined CI/CD pipeline

In our engagement with the client, we developed an advanced and scalable infrastructure to support personalized medicine software with health recommendations. “Emphasizing Infrastructure as Code (IaC) practices, we combined the power of AWS CDK with TypeScript. This enabled us to create a robust, serverless framework capable of handling complex recommendation and notification processes, integral to enhancing health management. Our team also focused extensively on testing mobile applications and back-end systems.

Infrastructure deployment

In the foundational phase of our development process, we deployed the AWS Cloud Development Kit (CDK) with TypeScript. This strategic choice allowed us to script cloud infrastructure as if it were software. It streamlined the creation of resources and ensured that our setup was maintainable and easily scalable — crucial for a system designed to handle a growing number of users.The infrastructure’s backbone was a serverless architecture designed for high availability and cost-efficiency. Serverless computing enabled us to build and run applications without thinking about servers. This meant we could focus on the core product without the overhead of managing infrastructure.To weave together the diverse actions and services the application requires, we leveraged AWS Step Functions to create State Machines. They ensured that each user interaction was processed accurately, triggering the correct sequence of events — from data ingestion to personalized JIT (Just In Time)-notifications and recommendations.
Our team embraced Python for its simplicity and efficiency in crafting Lambda functions, which formed the core of various back-end services. These functions were responsible for the entire user notification process, from data processing to sending out health recommendations and messages.Our PHP development team enhanced the UI of a web application using October CMS, focusing on a user-friendly system for managing notification data, including templates, placeholders, and conditions. This shift from a developer-reliant model to a more accessible approach has empowered product owners to manage data independently, streamlining the workflow and increasing efficiency in the notification management process.The complexity of transforming raw user data into insights called for robust ETL processes. AWS Glue provided a managed ETL service that simplified the preparation and loading of data for analysis. To manage the data flow in real-time, we constructed Data Pipelines incorporating services like AWS EventBridge for event bus routing and AWS Kinesis for handling massive health data streams, ensuring that user interactions were processed and acted upon without delay.

Continuous integration and deployment

To maintain consistency and quality in our deployment processes, we established CI/CD pipelines utilizing Bitbucket for source control and AWS CodePipeline for orchestrating the builds, tests, and deployments. These pipelines facilitated a smooth transition from development to production, with automated steps that reduced human error and streamlined releases.

Amazon Elastic Container Service (ECS) was configured to run and manage our Docker containers. This service simplified the system’s container orchestration, allowing us to deploy, manage, and scale the recommendation and notification systems with ease.

Quality assurance

Quality assurance was a critical and integral component throughout our deployment process. Our QA engineers validated the back-end system’s functionality, performance, and usability and ensured the mobile application’s highest quality by combining manual and automated testing methods.

A key focus of our QA strategy was the thorough testing of the personalized medicine software on mobile platforms. We conducted extensive manual testing by simulating real-world user scenarios to ensure the app’s interface and features worked flawlessly on various devices. This was complemented by running automated tests to cover a broader range of use cases.

Managing the CI/CD workflows was another vital aspect of our QA process. We monitored these workflows to prevent untested or buggy code from being deployed to production. This approach became especially crucial after identifying process gaps that allowed bugs to emerge in the live application, particularly during the critical 2.0 release for the new market.

To further refine the application based on user interaction, we implemented A/B testing mechanisms. This enhanced user engagement and provided valuable insights into user behavior and preferences, enabling the client to make data-driven improvements to their product.

The client was particularly impressed with the robustness of our mobile and back-end testing, as well as the efficiency of the CI/CD pipeline. These efforts led to a significant decrease in deployment-related issues and a substantial increase in the mHealth application’s stability.
