We implemented the WebRTC-based LiveKit framework to facilitate real-time video communication. This framework was chosen for its robustness and ability to handle live video streams efficiently, ensuring that seniors could engage in video calls effortlessly, with features such as auto-answer for ease of use.

The backend was developed using NodeJS, which provided the necessary scalability and performance to handle multiple user interactions simultaneously. Socket technology was integrated for real-time communication capabilities, ensuring that message exchanges and video calls occurred without delay.

Using Flutter, we developed applications that worked seamlessly on both iOS and Android platforms, ensuring a wide range of device compatibility. This approach allowed family members, caregivers, and seniors to use their existing devices to access Digihappy services without requiring additional hardware investments.

To cater to Digihappy’s diverse user base, we developed the application in English, Swedish, and Finnish. This multilingual support was crucial for ensuring that the app was accessible and usable for non-English speaking seniors, thereby expanding the service’s reach.

We implemented comprehensive security measures using AWS services. AWS CloudWatch was used for monitoring and logging the application’s performance, S3 buckets for secure data storage, EC2 for scalable computing capacity, and RDS for reliable database services. This not only ensured data security but also compliance with best practices in cloud infrastructure.

Using AppCircle for CI/CD, we ensured that updates and new features were rolled out smoothly and without disrupting the service. This tool allowed for continuous updates, bug fixes, and feature enhancements to be deployed efficiently.

The UI was carefully designed to be senior-friendly, incorporating large buttons, high-contrast visuals, and simple navigation paths. We conducted extensive UX testing with seniors to ensure that the design was intuitive and met their specific needs.

We integrated Scalefusion, a Mobile Device Management (MDM) service, to manage tablet devices remotely. This was particularly important for providing IT support and troubleshooting without needing physical access to the devices, thus simplifying the management of the tablets.

Our project team included two Flutter developers, one UI designer, one senior backend developer, one front-end developer, and one QA specialist. This team worked closely with Digihappy’s founder, Tiina, and COO, Johanna, through a fixed cost project initially, which later shifted to an Agile dedicated manpower model to allow for flexibility in response to evolving project needs.
