Case Study by Techstack

We have developed an iOS app for the entertainment industry in collaboration with our US-based partner. This solution is a decentralized blockchain network that enables sports fans to connect and share videos and fan cards. Thanks to the redefined product architecture, infrastructure costs have been reduced by 20-30 percent, creating a highly customizable and engaging platform.

User experience

Our primary objective as a mobile application and software development company was to create an unparalleled and truly immersive experience for sports enthusiasts. In pursuit of this goal, we dedicated our efforts to developing a dynamic environment that engages them on multiple levels, catering to their passion for sports through meticulously crafted features and interactive elements.

Moving to IaaS

To overcome code quality, architecture, and deadline challenges, we implemented effective measures for process improvement, code enhancement, and scalability. Our approach involved adopting serverless architecture, utilizing Terrasoft for infrastructure management, and implementing fault isolation through availability zones in the application that decreased the infrastructure costs by 20-30 percent.

Third-party services

The platform was seamlessly integrated with third-party services such as Sendbird, Twilio, and Zoom into our product modules. To efficiently manage resources, we have established a centralized warehouse that ensures consistent data aggregation and storage across all third-party platforms.
