The Challenge
Our client, an established ticketing company serving the events industry, faced a critical situation with multiple interconnected challenges:
- Legacy Technology Stack The system was built on an obsolete programming language version that was no longer supported
- Accumulated Technical Debt Over a decade of development had created a complex web of dependencies and inefficient code
- Impending Deadline A major event scheduled just one quarter away required the system to handle unprecedented ticket sales volume
- Performance Issues The existing system frequently experienced errors and slow response times during normal operations
- Scaling Limitations The current architecture couldn't support the anticipated load for the upcoming record-setting event
- Operational Impact Sales and support teams were losing productivity due to system unreliability
- Reporting Delays Management was experiencing delays in accessing critical business reports
With limited time and the pressure of a potentially record-breaking event, the client needed a strategic approach that could deliver immediate performance improvements while laying the foundation for future system enhancements.
Our Solution
We implemented a targeted optimization strategy focused on critical performance improvements within the tight timeframe:
Strategic Technical Assessment and Guidance
- Comprehensive assessment of the existing system architecture
- Identification of critical dependencies and bottlenecks blocking upgrade processes
- Development of a prioritized optimization roadmap
- Establishment of coding standards and best practices
- Creation of technical documentation for future development efforts
System Stabilization and Performance Enhancement
- Strategic untangling of complex dependencies that were blocking system improvements
- Implementation of cache-aside caching strategy to reduce database load
- Optimization of database queries and data access patterns
- Performance monitoring and alerting systems
- Load testing framework for capacity validation
Asynchronous Processing and Development Environment Improvements
- Design and implementation of queue-based processing systems
- Separation of synchronous and asynchronous operations for improved responsiveness
- Consolidation and standardization of local development environments across teams
- Implementation of consistent development tooling and workflows
- Streamlined onboarding process for new developers
