Re-architecting a High-Load Real-Time Web Application with React and TypeScript(NDA)
GamingA case study of rewriting a legacy frontend into a modern React/TypeScript stack, implementing real-time interactions via WebSockets, and introducing a scalable SPA architecture.
Project Overview
Interactive Gaming Platform / Real-Time Web Application
The client-facing side of a high-load web service with real-time updates, authentication, a personal account area, financial interfaces, and a communication system.
Team role: Frontend development and UX/UI design.
Context and Business Challenge
The project was an interactive gaming web platform with a wide range of user flows and real-time interactions.
At the project start, the client-side application was built with plain HTML / CSS / JavaScript, without modern frameworks. This caused several issues:
- •Difficult product maintenance and evolution
- •High technical debt
- •Unstable real-time interfaces
- •Challenges with scaling and adding new features
- •No unified UI architecture
The business goal was to rewrite and modernize the frontend, creating a robust architecture for long-term platform growth.
Project Goals
Delivered Solution
Frontend Redesign and Re-architecture
- Full user interface redesign
- Complete frontend rewrite from scratch in React and TypeScript
- Design system planning and implementation
- Modular UI component architecture
- Frontend prepared for scalable product evolution
Authentication and User Account Area
- Registration and authentication flows
- User session management
- Personal account area with activity history and security settings
- Profile and user data management
Real-Time Interaction (WebSockets)
The project included a full WebSockets-based real-time architecture:
This made it possible to:
- •minimize the number of REST requests
- •reduce server load
- •provide a highly responsive interface
API Integration
Platform Functional Modules
The platform included a broad set of interface modules:
On the frontend side, we implemented:
- •complex user states
- •animations
- •dynamic interfaces
- •real-time data synchronization with the server
Development Process
The project was delivered iteratively in sprints:
Analysis of legacy code and architecture
Design of the new client-side architecture
Implementation of the core UI framework
Integration of real-time modules
Implementation of key user scenarios
Performance optimization
Final stabilization and ongoing support

Summary
As a result of the project, a modern frontend for an interactive web platform was delivered, fully rewritten in React and TypeScript.
The updated architecture provided:
- high performance
- stable real-time functionality
- easier maintenance
- flexibility for further product development
The project is currently in the stage of active support and feature expansion.
