Case Study: Shift improves observability and error monitoring with Sentry

How Shift Improved Observability while migrating from a Monolith to Microservices

Shift, the fast-growing used-car e-commerce company, was migrating from a legacy monolith to microservices and needed much better observability across both old and new systems. Its homegrown error-tracking tools were hard to maintain, delayed notifications, and made it difficult for engineers to know how releases were performing in real time. Sentry was the vendor involved, and Shift needed a managed monitoring solution to help its team stay focused on the customer experience.

Sentry was reimplemented properly with Slack alerts, error tracking, performance monitoring, and mobile application monitoring, giving Shift timely notifications and a complete view of issues in production. As a result, engineers could respond faster, prioritize work more effectively, and monitor releases with confidence. The measurable impact was more reliable alerts, manageable error volumes, fewer undetected errors, and improved efficiency as Shift retired its custom tools and gained real-time visibility.
