Experience the cutting-edge benefits our clients enjoy globally from the Toptal network.
Challenge: The company struggled with high-volume performance issues, unstable infrastructure, and leadership hesitancy around major code changes, hindering scalability and the customer experience.
Solution: Toptal built leadership trust through an incremental optimization strategy, implementing small but continuous SQL improvements and monitoring live system performance to pinpoint high-impact inefficiencies. As part of this approach, the team refactored a frequently executed query and its underlying data structure using SQL Server best practices, achieving three times faster execution and smoother system operations.
Outcome: Improved stability and system efficiency drove a 400% increase in platform usage and boosted confidence in Toptal’s recommendations. Targeted back-end changes resolved key bottlenecks and established a technical foundation for reliable scaling and future growth.
