I have extensive experience with various APM tools such as New Relic and AppDynamics. In my previous role, I implemented New Relic to monitor our application's performance, identify bottlenecks, and optimize response times. This resulted in a 20% improvement in application efficiency and significantly reduced downtime.

I prioritize tasks based on their impact and urgency. Critical issues that affect business operations are addressed immediately, followed by high-priority enhancements. I use a ticketing system to track and manage tasks, ensuring transparency and timely resolution. Regular communication with stakeholders helps me stay aligned with business needs.

I follow industry best practices such as regular security audits, vulnerability assessments, and implementing the principle of least privilege. I also stay updated with the latest security patches and ensure they are applied promptly. Collaborating with the security team helps in identifying and mitigating potential risks proactively.

In such scenarios, I first roll back the update to stabilize the application. I then conduct a thorough root cause analysis to understand the issue. Collaborating with the development team, we identify fixes and test them rigorously before deploying a stable update. Clear communication with stakeholders is maintained throughout the process.

In my previous role, I noticed users were struggling with the application's interface. I conducted user feedback sessions and used the insights to propose UI/UX improvements. These changes included simplifying navigation and enhancing visual elements. The result was a 30% increase in user satisfaction and a more intuitive user experience.
