Software Engineer
MuleSoft (Salesforce)
04.2022 - 05.2025
- Production Observability: Led the Critical User Journeys (CUJ) program and achieved 99.95% Availability by creating Synthetic Monitoring tests for 80% of MuleSoft AoV Products. Improved diagnosability and Performance bottlenecks.
- Cloud Infrastructure CTS: Helped in $2M cost savings by identifying and decommissioning stale Kubernetes pods having low CPU and Memory usage.
- Performance and Scalability: Gathered and analyzed non-functional test requirements, including system workload modeling, user load, SLAs, and infrastructure specifications.
- Developed strategies and plans for performance benchmarking of MuleSoft product features, including load, scalability, stability, reliability, and limits testing.
- Designed and executed performance tests (load, scalability, stress, reliability) to evaluate system behavior under high demand using JMeter.
- Leveraging NewRelic, Splunk, Grafana and in-house Salesforce Monitoring APM dashboards to collect, analyze, and report performance test metrics, identifying system bottlenecks (CPU, Memory Leaks and Thread Contention).
- Generated detailed performance analysis report with actionable recommendations and collaborated with the engineering team to optimize system performance.
- Setting up the performance infrastructure resembles the customer environment (On-Prem, Hybrid, Cloud migrations) and conducts root cause analysis of PROD issues and helps the team to resolve them.
- Simulated and executed load across MuleSoft platform during chaos engineering experiments, and analyzed system resilience and recovery strategies.
- Developed test automation frameworks using Java and integrated into CI/CD pipelines for early performance validation.
- Conducted peer code reviews to ensure load test scripting standards and maintained scripting standards and efficiency.
- Participated in Agile ceremonies and collaborated closely with developers and architects to embed performance early in the SDLC.
- Managing Escalations: Triaged JIRA tickets, resolved high-priority issues, and collaborated with engineering teams to fix bugs. Monitored and analyzed the performance of products using logs, metrics and various tools. Identified gaps in test coverage—leading to a 50% increase in pre-release defect detection.
