Own the performance aspect of different Supply Chain Management services end-to-end starting from design phase to production monitoring and bug resolution.

Benchmark performance and scalibilty of distributed and containerized services and resolve any bottlenecks with heap dump, thread dump, strace and AWR analysis.

Recommend core, memory and other critical parameters of distributed kubernetes workloads with kafka parameters to optimize cost and maintain high availbility.

Design and script complex Jmeter performance Test script for various SCM services and scenarios. Carry out different types of PT and monitoring crtitcal metrics in Grafana, Appdynamics. Analyze and resolve Production issues with ELK log analysis and dashboarding.

Testing performance of on-prem monolithic services being migrated to cloud based kubernetes workload.

• Benchmark performance of complex ordering web application for telecom client. Application was completely containerized on open-shift cloud.
• Building new Jmeter test scripts and maintaining regression suite on containerized Jmeter instance with ELK to analyze results.
• Machine Learning: Building a ML model for predictive analysis of streaming data.

• Benchmarking and resolving performance bottlenecks for N-tier applications as well as isolated components for both monolithic and microservice architecture.
• Resolving Non-Functional requirement, creating test scripts and delivering performance test result for various banking, telecom and retail domain applications.
• DevOPS: Designing and implementing end to end performance test automation framework integrating performance testing phase with CI/CD pipeline. The framework required integration of Jmeter/Loadrunner with Github, Jenkins, Jira and other management dashboard using python scripts.
• Scalability testing for Cloud based Applications.
• Setting up the entire open source performance test tooling suite with Jmeter, Grafana, TICK stack, wiremock, Jenkins, perfmon/nmon, etc.
• Performance tuning of different layer of application by analyzing server metrics through different APM (AppD,Dynatrace, perfmon) and AWR/ DB query analysis.
• Leading a Microfocus Performance Center/ Loadrunner enterprise migration project which included installing complete software suite and migrating a huge volume of existing data.
