Senior AI Engineer Mphasis, New York, NY 07/2020 - Present
Mphasis Limited is an Indian multinational information technology services and consulting company. Product teams often struggle to balance between release frequency and defect leakage. The trade-off is difficult to manage for teams involved in testing of products with many possible configurations, products with third-party dependency, products that need specific equipment and lab set-up, and hardware products. While almost every organization wants to achieve 100% test automation, not all product teams within the enterprise can achieve that due to the inherent nature of the products. To improve the quality of the testing and optimize beyond test automation, it is useful to use historical data to bring in the power of Artificial Intelligence and Machine Learning (AI/ML). As a Senior AI Engineer in the Mphasis Cognitive Quality Engineering Group, I led a team of Data Scientists, Machine Learning Engineers, and Data Engineers to design, build. and deploy AI automation solutions specific for manufacturing problems.
