• Java8 | JavaAgent | DropWizard | Docker | Kubernetes | BitBucket | Java Concurrency | Maven
• Designed and developed a Java Agent with the purpose of monitoring server performance. This Java Agent is capable of collecting various performance metrics for a given request, such as stack trace, CPU usage, memory usage, and GC overheads.
• Implemented a strategy to process ~10K requests a minute and export filtered data to object collector asynchronously
• Developed an algorithm that enables a Java agent to maintain its CPU and memory overhead within pre-defined thresholds. This algorithm continuously monitors the agent's resource usage and adjusts its behavior dynamically to ensure that it remains within the allowed limits.
