Challenges & Solutions
Challenges
Low-functioning user chat
Users experienced delays, message loss, and unclear errors. Meanwhile, the team lacked tools to monitor and fix issues due to the non-transparent nature of the system.
Low performance under load
The platform struggled to maintain speed and stability during high user activity. Page loads slowed down, APIs responded poorly, and system reliability decreased.
Lack of structured tech system and processes
The platforms' tech setup lacked unified documentation, ownership, and structured workflows. It has led to delays in problem resolution and difficulties with scaling and onboarding.

Solutions
Fully customized chat with future cross-solution integration and scaling
We built a custom chat from scratch to replace an unreliable one, giving our customers full control and real-time monitoring. It integrates seamlessly with other services and supports scalable, high-performance communication.
Migration from Rails Monolith to Fast, Flexible GraphQL API
We migrated from a monolithic Ruby on Rails app to a React SPA and built a GraphQL API to support it. This helped us reduce data payloads, improve front-end/back-end communication, and boost overall system performance.
Scalable & reliable tech processes with AWS Best Practices
By following AWS best practices, we introduced detailed technical documentation, defined service ownership, and implemented incident/change management.

main features
Scalable and fully custom real-time chat
The chat is fully integrated with the platform, offers real-time communication without delays, and is built for future scalability to all company's services. As a result, users can now enjoy a faster, reliable messaging experience, while the support team gains full visibility and control for easier maintenance and issue resolution.
Optimized Platform Performance with a Custom GraphQL API
We built a separate GraphQL API to support the migration from legacy REST endpoints, helping reduce data payloads, streamline client-server communication, and significantly improve platform performance during high-load periods.
Auto-scalable & cost-optimized AWS-based architecture
We optimized the infrastructure using AWS best practices. Services are now auto-scalable, fault-tolerant and cost-optimized. Ownership was introduced — each service has a responsible person and documentation, which improves transparency and supports quality.
