We were approached by a client who was developing a system to record a patient’s activity and blood chemistry from wearable medical devices. This data, and analysis of it, would be provided to clinicians to help them monitor and advise their patients. Seeking to create a new layer of value, the client requested our help to gather data from patients and make it available to clinical organizations, with data subject to privacy rules and reliability guidelines, on a robust yet highly secure online system.
The client’s platform was designed to enable greater access for physicians to their patient’s health data. This data would be collected from patients wearing devices, and it was to uploaded to a cloud based infrastructure over commodity smart phones (iOS/Android). All the data collected would need to conform to stringent European Union mandated privacy guidelines regarding its storage in the cloud and transmission. Furthermore, the client needed secure web portals and mobile applications for authorized physicians to visualize and interpret a patient’s data. They had little cloud infrastructure in place to start with, and no satisfactory front-end technology. They needed to quickly demonstrate progress to investors.
The client outlined several requirements for the platform: Develop a medically compliant cloud infrastructure that is both secure and scalable Develop back-end services capable of receiving from many connected devices Develop web and mobile clients for both patients and physicians Integrate with existing OAuth2 authenticated APIs to connect with off-the-shelf medical devices and other cloud services Develop data cleansing and parsing modules for raw device data Implement custom machine learning modules to analyze data Integrate with existing cloud analytics platforms
Our full-stack solution was developed iteratively with the client. We delivered a custom software infrastructure applying Agile development practices to help them meet their development and financing milestones.
Since working with us, the client has gone on to secure additional funding from major corporate partners to further develop their platform. We have also provided training to the client’s engineering department, educating them on state of the art engineering practices. We have provided documentation and tools enabling them to expand their own team. Our mathematicians on staff have advised the client on advanced machine learning techniques, and developed custom modules. Our Devops team has delivered to the client a cloud based solution hosting a custom REST and WebSocket API for transmitting the data. The solution includes extensive devops automation to ensure the client will be able to accommodate additional demand.
Throughout the engagement that client was consistently satisfied with our ability to rapidly prototype solutions, and then ramp up development in business critical areas. All of our goals were accomplished under budget, demonstrating our ability to deeply embed with a client to deliver an IT solution. The client continues to use our services advising on technology and delivering custom software enhancements.
