Mr. VENKAT CHINTHA

Responsible for driving and Executing 5G Interoperability Testing and Early Device Integration of Nokia 5G products with UE/Chipsets Responsible for Integration of the code and Automation testing for various Requirements. Created automated test suite utilizing a keyword-driven automation framework called Robot Framework. Developed accurate and efficient test scripts in Python and Robot Framework to manage automated testing of certain products and features. Build and improve the existing automation framework based on Python. This involves writing feature files, developing new methods, and automating TCs using ROBOT Contribution towards bringing up the Test Automation framework to execute the Test Cases in completely automated way using ROBOT FRAMEWORK Automated most of the regression test cases using ROBOT FRAMEWORK to smooth delivery of the SW in faster way Extensive device driver development and support in 3G/4G/5G, and power management Applied data visualization to compare the Different RF performance parameters with the Golden benchmark values across varied dimensions using PowerBI and Python Experienced in deploying CNFs to cloud environment using Devops tools like Docker, Kubernetes, Jenkins. Development of ConfigMaps, Secrets, Service Accounts, Roles, Cluster roles, Role Bindings, Cluster Role Bindings on Kubernetes Use of Vault for storing environment variables, Secrets for the applications which are pulled and used by the applications during deployments. Experienced in orchestration using Kubernetes. Use of Multiple Devops tools for Orchestration to easily deploy into production network. Use of docker for container orchestration Development of Kubernetes Dashboards for user to interact and view the first level of service health status. Development of Kubernetes monitoring dashboards using Prometheus and Grafana. Experienced in deploying AMF, PCRF, NRF and other Network Functions Use of Docker, Docker Compose and local Kubernetes as development environment for developed microservices. Use of Helm charts for deploying the applications and maintain helm chart repository. Use of Docker, Docker Compose and local Kubernetes as development environment for developed microservices Migration of applications form Elastic Beanstalk managed ec2 instances to Kubernetes on AWS using EKS services. Used Jenkins pipelines to drive all microservices builds out to the Docker registry and then deployed to Kubernetes. Involved in deployment and testing of 5G network components like AMF, SMF, UPF, UDSF and debug 5G NR related flows Experienced in testing EPC functionalities. Good Knowledge on Spirent landslide Created use cases and test plans for end-to-end system verification. The test plan scope includes basic RAN and packet core functionalities (LTE/UMTS/CDMA, SGSN/MME, GGSN/PGW, PCRF, MSC), IMS and CS Voice call features (basic calls, supplementary services, handover, conference, call feature provisioning, circuit switch network break in/out, E911, etc.), IMS SMS/MMS and RCS (chat, file transfer, presence, etc.) Examining HW and SW performance of the SGSN and providing recommendations to customers to improve the performance of the SGSN Coordinate with the chipset/device vendor and Internal R&D teams on the IODT execution and troubleshooting Analyze various gNB and UE logs (e.g. wireshark /syslogs/BIP traces/ BTS Snapshot/Component traces) for fault investigation and determine root cause analysis of the issue Responsible for the tracking of faults and driving to resolution for both internal and the specific vendor and provide regular updates to Management. Developed test automation framework scripts using Python Selenium WebDriver, Developed and maintained reports of all automation issues and test results Updating the Test Automation suite regularly to ensure its accuracy and usefulness. Created XML based test suit and integrated with Jenkins Server to execute automation scripts on a regular basis by scheduling Jenkins jobs in different test environments with different test configurations. Track automation results daily for better performance in testing. Interfacing with the IODT execution teams on a day-to-day IODT activities, deliverables, timelines, and reporting Creates IOT Program Plans, test plan, test report to ensure testing capability meets Nokia requirement. Manages IOT Program deliveries to ensure projects are completed on time and per the process. Engage with Mobile Network Operators, Customer teams, Product Management as well as Chipset vendors to receive, analyze, discuss IODT requirements which are incorporated into the IODT execution plan. System Integration activities with ongoing 3GPP Rel-15 feature requirements & identification for both cmW and mmW product solutions. Documentation and development of test plan, test strategy, optimization, and test automation. Feature Testing for 3GPP NR Rel 15. For both SA (option 2) / NSA - option 3X (LTE-5G) system configuration / feature scenarios. Troubleshooting and log analysis for the issues found during the testing of Nokia Products and Chipset Vendors Technical Root Cause Analysis from the Entity Test/ MAC Layer perspective, in parallel with RRC, PDCP, RLC and PHY layers. End-to-End IP connectivity validation between SGSN-MME and end IP nodes like RNC, GGSN, eNodeB, SGW, DNS, OSS, etc; Working on core issues due to AMF stability Software Regression Tests on Nokia Airscale and Airframe customer product solutions. Working in an Agile environment and a stakeholder in the 5G Software Product development cycle. Writing of Test scripts in Python (Test Automation purposes) Execution of test scripts using the Robot Framework and identifying / solving of problems
