WHY ORGANIZATIONS CHOOSE US
Toptal in Action
Discover the cutting-edge benefits our clients enjoy from the global Toptal network.
Toptal full-stack experts clear 6 months of backlogged bugs in 6 weeks.
Challenge: Software defects can cause critical errors and widespread user dissatisfaction for tech brands. A big data software provider was facing a six-month backlog of these defects, reported by its top clients. Its engineers were overwhelmed, trying to simultaneously address incoming reports and product development—reducing productivity and fueling staff turnover.
Solution: In only six weeks, Toptal’s team cleared the six-month backlog while simultaneously processing day-to-day tickets. In a 14-month span, they resolved 266 top-priority product defects and managed countless daily tasks.
Outcome: Toptal’s solution enabled the software provider to improve the end-user experience across all products. Toptal’s experts are now training a dedicated in-house team to transition to a scalable ticket processing system.
Clement [technical lead from Toptal] is doing excellent work, especially with landing the most difficult tickets. He delivers early, proactively seeks out ways to help others, and is a super performer.
