Rollbar experienced a transformative year, marked by significant platform modernization and expansion efforts to stay ahead in the competitive Error Monitoring space. The engineering team doubled in size to address the growing demand, focusing on improving real-time error processing and reducing noise through enhanced classification and automatic merging capabilities. A strategic acquisition of SameBug strengthened Rollbar's AI and classification expertise, leading to innovations like the Apache Spark integration, which improved error management. The company transitioned to a microservices architecture, leveraging Kubernetes and Google Cloud for scalability, and revamped its user experience with a focus on multi-project functionality and a single-page app approach. These developments were supported by a new Docker-based development environment, enhancing speed and onboarding efficiency. The shift to distributed service ownership empowered engineers to take full responsibility for platform health, with all teams now on-call. Looking ahead, Rollbar anticipates new challenges and opportunities, driven by a workforce that will predominantly consist of recent hires, reflecting a dynamic phase of growth and innovation.
