In various pilot programs, I contributed to the analysis of purchase decision metrics and license acquisition numbers to support strategic tool selection. Worked with cross-functional teams to evaluate metrics and ensure full project understanding. Performed extensive database analysis, thoroughly documenting analyses and designing efficient schemas and tables. Using AWS and Minio, I created databases and automated tasks using Excel report analysis. Using Python ETL jobs, I migrated to OpenShift and implemented CI/CD for code quality. I configured and monitored Jenkins jobs, automated financial activities, and managed APIs using Python scripts. Effective communication led to proposing innovative solutions and presenting results to stakeholders. I developed Python applications using Flask and provided technical guidance and support. Using Superset and Starburst facilitated data visualization and manipulation. My experience spans relational and non-relational databases, including Cloudant, Hive, MySQL, PostgreSQL, DB2, and Netezza. User support via ServiceNow, API testing with Postman, and Docker image creation were part of my responsibilities. Configuration and monitoring of Kubernetes pods, as well as using Trino for database manipulation, were also part of my responsibilities. Supporting the Tech Lead, I gained valuable experience in team management and optimization, improving process performance and efficiency through query optimization and code template development.
