91%

message delivery reliability, up from ~55%

98%

session stability was achieved

75%

faster incident resolution time

Description

Softacom was approached by the developer of a healthcare application from the US. The company helps clinics and patients manage health data and communicate securely. They faced challenges when implementing complex integrations and resolving technical issues. As a result, these problems were blocking the further development process.

The goal was to enable secure data exchange with external services, improve communication between users and medical staff and enhance system reliability through custom solutions such as advanced messaging using a newly developed SMTP gateway and file logging, and mobile functionality improvements.

The client also asked Softacom to develop sample implementations of various features that the client could later integrate into their main product independently.

See how we can stabilize healthcare messaging and integrations in your application.

Challenges

The client’s app couldn’t connect to other medical platforms, which prevented data exchange and limited the product’s usefulness for clinics and patients.
The application’s architecture required deep customization. Missing configurations and unsupported features (like cookie handling on Android) caused authentication failures and blocked further development.
Key functionality, such as file and attachment sharing, was missing. This damaged trust and usability for medical professionals.
The existing email-sending mechanism was unreliable and couldn’t meet healthcare-grade security or delivery requirements. It showed errors in up to 45% of messages.
The lack of proper logging and file transmission tools made it difficult to track activity, verify transactions or quickly diagnose system issues.

Solutions

To resolve the client’s integration and technical challenges, Softacom designed and implemented a series of solutions and established a collaboration process for continuous improvement.

To solve the problem of integration with third-party healthcare services, our engineers built an integration layer between the application’s backend for client’s mobile app and external healthcare services and delivered without downtime. The solution managed authentication, encryption and data synchronization. This enabled compliance with the secure exchange of data between systems.

The healthcare app needed to function reliably on Android devices used by both patients and clinicians. Since the existing core lacked cookie handling for Android’s webview, Softacom developed a custom implementation that ensured 98% session stability across devices. This improvement increased security and ensured clinicians and patients could reliably use the app on Android devices.

Softacom team created a dedicated SMTP gateway adapted to the client’s infrastructure to replace unstable third-party APIs. Message delivery reliability improved from ~55% to 91%. That gave the client control and secure delivery of medical notifications and reports.

An internal module was created to record all system events and manage secure file transmission. This increased transparency, simplified troubleshooting and provided an auditable record. This also reduced incident resolution time by ~75%.

At the client’s request, Softacom developed a set of sample modules demonstrating how to implement new features. These samples served as ready-to-use templates, allowing the client’s own team to integrate new functionality independently in the future. The whole process was accelerated by up to 40%.

We also continue our partnership with this client, working in an iterative monthly process.

Outcomes

As a result of Softacom’s work, the client was able to resume active development of their application and move forward with new functionality. The project unblocked development and restored progress on the healthcare app’s roadmap, allowing the client to deliver new features faster.

The new integration layer established secure, compliant data exchange with external systems.
The custom SMTP gateway improved message delivery reliability from ~55% to 91%. The new logging and monitoring system reduced incident resolution time by approximately 75%. This allowed the client’s small team to focus on developing new features instead of fixing recurring issues.
Android fixes achieved 98% session stability and improved usability for doctors and patients, strengthening user trust.
Improved Android WebView and security enhancements ensured reliable use across the wide range of Android devices commonly used in clinics and by patients.
The reusable feature modules accelerated internal development by up to 40%. This helped the client’s team implement new functionality independently and reduce long-term reliance on external contractors.
The established iterative collaboration process ensured predictable delivery and transparent communication.

Softacom continues to support the client through regular development cycles. This helps them enhance the application without disrupting the whole process.
