Platform Modernization for Scalable Online Auction System

The current online auction platform is built on legacy code that limits scalability, hampers development efficiency, and complicates feature implementation. This technical debt results in reduced system performance, increased maintenance costs, and inhibits the platform’s ability to handle increasing user demand and support future growth. Additionally, mixed-language code and poorly documented components further hinder effective system updates and reliability.

A mid-sized public sector organization operating an online auction platform to sell goods from various sectors, aiming to support growth and improve system reliability.

• Modernize the existing codebase to improve scalability and maintainability, enabling the platform to support a growing number of users and transactions.
• Reduce system maintenance costs and technical debt through comprehensive code refactoring.
• Enhance development efficiency by standardizing components and adopting modern development frameworks and tools.
• Improve platform stability, speed, and user experience for both buyers and sellers.
• Prepare the platform infrastructure for future feature expansion and integration needs.

• Refactoring of legacy code into modern programming standards, including transition to strongly typed languages or frameworks (e.g., TypeScript).
• Development of a standardized, reusable component library for UI/UX consistency and development speed.
• Migration of state management from outdated libraries to modern solutions such as Redux Toolkit.
• Implementation of a flexible backend interface capable of handling increased transaction volumes and concurrent users.
• Enhanced system documentation and dependency analysis tools to facilitate future maintenance.
• Support for multilingual codebases, including accurate interpretation and updates across different language segments.

• Backend data systems delivering information in multiple languages
• Existing payment gateways and transaction processing modules
• Authentication and user management services

• Support for increasing user load with seamless scalability
• Platform speed improvements to reduce latency in bidding and listing operations
• System reliability with high availability and minimal downtime
• Maintainability through code clarity, documentation, and dependency management

The refactoring and modernization effort is expected to significantly enhance the platform’s stability, speed, and scalability. Target outcomes include a reduction in technical maintenance costs, support for increased user demand, and quicker deployment of new features. Initial modernization of approximately 25% of the codebase demonstrated measurable improvements in system stability and performance, laying the foundation for complete platform overhaul and future growth readiness.
