Message

At Accenture Japan, I developed metadata-driven automation for migrating enterprise data from IBM DB2 to Amazon Aurora PostgreSQL, including scripts to create and run 200+ AWS DMS tasks. I also developed migration utilities and data validation frameworks for large datasets.

At Cognizant, I developed Adobe AEM components and translation integrations, and built an RAG search application using Flask and Azure OpenAI. Earlier, at LTIMindtree and Tata Consultancy Services, I developed AEM solutions and Java- and Python-based applications, including a merit-list solution that served over a million candidates.
