Awards: Diamond eRecognition award and Performance award for Excellent problem solving1. Lead Performance test and engineering activities to transform legacy mainframe DB2 system into Java, Oracle and Kubernetes (Docker) driven based Microservice system. 2. Performance tune modernized batch processes to fit the on-going Mainframe system batch window. Design Performance models to determine the data processing and performance statistics of batch jobs before actual testing. Models identified the need for High Availability and application design changes to meet business SLA and saved about 3 months of Production delay to program. 3. Innovated and standardized Test requirements gathering process for scripts development and test data. Test scripts development effort by the team for sprint reduced from 60 hours to 24 hours.4. Implement Continuous Integration and Continuous Deployment (CICD) process in DevOps based work culture to deliver updated application every day to the end-user.5. Optimize applications regularly by identifying and mitigating bottlenecks to improve the end-user experience using tools like Dynatrace, Splunk, Elastic-Log search, Heap Analyzer etc.6. Lead and Execute the performance and resiliency testing of system's APIs/components/services/applications and infrastructureWork Environment Technologies: Apache JMeter, OpenShift Kubernetes, Spring boot, Zulu, Jenkins Continuous Integration and Continuous Deployment (CICD), Dynatrace, Splunk.

• Successful implementation of Software Test Life Cycle and delivery of high quality application by working with onshore and offshore teams.• Had setup test environment and test data for Performance and Functional tests. • Configured AppDynamics, CA Intrascope and other application monitoring tools in the test environment. Root cause investigation time reduced from 48 hours effort to 12 hours.• Designed Workload model, test plans and strategies for functional and performance testing of applications (thick and thin) hosted in the premises and cloud (Azure, OpenShift and PCF)• Developed and updated processes related to code deployment and test execution regularly for efficient testing, analysis and reporting. Code deployment using IBM Urban deploy reduced from 6 hours to 2 hours effort. Test execution effort went down from 72 hours to 60 hours• Migrated test execution from HP tools like Load Runner and Performance Center to Apache JMeter. Company saved a budget of $100000• Set up and conduct Baseline, Load, Stress, Scalability, Endurance, Smoke, Functional, Resiliency, API etc. testing based on the requirements and delivery period. • Leverage available tools like AppDynamics, CA Introscope, Solar Winds, ELK stack etc. to perform analysis of the test results and determine bottlenecks, root cause of application degradation, bugs etc. Recommend the best solutions to development team.• Assist in the Disaster Recovery (DR) of applications by identifying the required test scenarios and conducting required tests for a successful DR.• Help the Business Intelligence team to test and validate that correct data and reports are generated by Tableau from Data Warehouse for the client. • Troubleshoot the defects identified in the Production within the allotted period of time by replicating the defects in Test environment and conducting series of tests.

1. Carried out Performance testing activities for SAP, Java and .Net applications.2. Gather test requirements for Performance test execution by working with Business, Infrastructure and Development teams.3. Analyse Non-functional requirements to design Workload model for effective Performance test execution4. Review developed Load Runner scripts and execute Performance tests. 5. Investigate the errors found during testing and identify the root cause of the errors using Application logs, App Dynamics etc.

• Led and trained graduate and undergraduate students on Electrical Characterization tools and techniques to analyze the huge test data each month.• Automated testing activities thereby improved the product delivery performance and period.• Managed vendors and team of graduates with tools installation, devices fabrication and testing for product delivery.• Conducted profiling, Reliability tests and Failure analysis of TFT, ferroelectric materials (FeRAM), and other semiconductor devices to review and analyze device performance. • Designed and developed test equipment, test structures, experiments and process flow for II-VI semiconductor TFTs and Ferroelectric materials. • Introduced new technologies and processes to researchers and recommend best practice to improve TFT and ferroelectric materials researches. • Collaborated and communicated effectively with researchers to determine and resolve problems in research regularly.

• Collaborated with country’s eminent scientists to design and deliver High Speed Remote Sensing Satellite.• Researched, identified and presented the effective methodologies to implement Randomizer for encryption.• Designed and developed Randomizer for signal encryption by coordinating with VLSI team and Satellite communication experts. • Designed and verified “High Speed Satellite Link Analyzer” using AHDL based on FPGA technology.• Performed link analysis and error correction for effective communication between ground station and satellites.

• Designed 5000 input-output Programmable Logic Controller (P.L.C) that handles all the nuclear reactor parts fabrication machines in one department.• Researched on PLCs and recommended the best practices to resolve problems with PLC at work.
