Global Retailer + mindit.io: Revitalizing Legacy Systems to Boost Performance and Scalability

About the client

Our client is a global retailer with a strong international footprint and a commitment to operational excellence across hundreds of stores. Their systems handle large volumes of transactions and user interactions daily, making performance and reliability non-negotiable.

A mission-critical web application, built on Java and backed by Microsoft SQL Server, had become increasingly unstable under pressure, leading to poor task execution times, failed requests, and bottlenecks that impacted both customer and employee experience.

/Key Results

Reduced task execution time across high-volume operations
Stabilized system for 60+ concurrent users
Increased success rate for user transactions
Agreed re-platforming plan for future scalability and modernization
Improved data accuracy and decision-making efficiency

/The Challenge

The legacy application presented several high-priority issues:

Low Success Rate: A growing number of unsuccessful user requests led to operational delays
Slow Task Execution: Time-sensitive operations were hampered by long execution times
Poor Concurrency Handling: The system struggled to support 60+ concurrent users without degrading performance

These challenges required both immediate remediation and a strategic vision for long-term platform modernization.

/Project Goals

mindit.io was brought in to:

Identify and eliminate performance bottlenecks in the current system
Improve execution speed and ensure reliability under user load
Propose a re-platforming strategy aligned with future growth and technology evolution
Enhance system-wide decision-making and operational accuracy

/mindit.io’s Solution

We adopted a multi-step approach to stabilize and optimize the legacy platform while building a strategic roadmap for the future:

In-Depth Analysis:
- Assessed Java application internals and SQL Server performance
- Identified code inefficiencies and costly database queries
Targeted Optimization:
- Fine-tuned SQL queries for faster data access
- Optimized memory handling in the Java backend
- Streamlined code execution paths for smoother performance
New Architecture Proposal:
- Recommended a re-platforming approach to address root causes
- Designed for scalability, performance, and long-term maintainability
Rigorous Testing & Validation:
- Conducted iterative testing after each improvement
- Ensured no regressions or unintended side effects occurred

/Results

The collaboration resulted in immediate performance wins and long-term alignment:

Improved Financial Outcomes:
- Better system performance enabled faster, more accurate decision-making
Reduced Operational Workflows:
- Optimizations reduced manual processes and saved time
Increased Data Accuracy:
- Automation reduced human error in transactional systems
Stronger Cross-Team Collaboration:
- Shared insights and streamlined communication enhanced alignment across teams
Re-Platforming Plan Secured:
- Client aligned with mindit.io on a future-proof architecture for modernization
