Worked as a member of the ML Growth Team in different capacities and projectsContributed to enhance relationship detection system using heuristic and machine learning from company homepages, by making it robust by improving its RESTAPI, system monitoring, and enhancing the analytical tracking of the overall system.Designed and contributed to developing event-driven system that reacts to changes in risk scores or user activities. This system is designed to automatically identify and extract relevant business relationships from corporate websites.Contributed to research and developing a proof of concept to detecting products and services from raw unstructured text and linking them to different classification ontologies through deep learning method as part of ML discovery team.Contributed to designing and developing a ML based entity resolution service using transformer, vector databases to resolve entity from a knowledge base of hundreds of millions of entities.

Worked and collaborated with the cross-business unit teams in developing python libraries for robotic process automation applications. Programmed shell scripts for automating daily activities related to operating system and Database. Conducted research with an interdisciplinary team of the database, operating systems and networking experts to optimize the performance of SAP data migration across data centers. Worked with solution architects in designing end-to-end implementation and configuration of SAP applications in complex environments. Enhanced SAP application capabilities with version upgrades, system refreshes and add-on installations. Provided operational support to client SAP environment, devised strategies for integration of SAP Infrastructure with add-on non-SAP tools, developed performance tuning analysis to prioritize the changes in the client’s SAP infrastructure to avoid application failure.
