Summary

Started my career as Business Tester and held varies roles managing testing, environment, defects, and deployment (IT and Networks). Then as an Operational Acceptance lead, my role was to control the quality aspects of the delivery by inspecting, reviewing, and validating functional, non-functional, operational requirements (incl. HS&E, Contracts, Supply chain, workforce, assurance readiness) at initial stage of the project and once the solution is ready, validate them by getting User Acceptance Testing(UAT) and Business Readiness Testing(BRT) performed by Operations SME's and based on Test Reports giving go-ahead for project deployment and volume rollout. Currently working as Network Transition Manager, in my current role, been recognized as a technical project manager responsible for managing end to end delivery of network solution for transformation, lifecycle upgrade, migration projects. Test Management and product ownership are core responsibilities in addition to Overall project management.
