Notable Achievements

Actively pitched PoC pilot initiatives by working closely with the client that directly led to the winning of new business.

Helped coordinate a cross-functional effort across geographies from gathering requirements to final deployment successfully in a very short ramp time that eventually won accolades from the CEO.

Identified process improvements that contributed to reduction in the defect turnover time by about 30 by driving the development of a tool that automatically gathered system error logs and created a single error report after an automated test case execution and thereby eliminating an additional manual overhead for the test engineer.
