These processes are primarily based on Oracle relational data sources.Currently, I am focused on two major projects:• Coordinating and collaborating to adapt the ETL processes of the corporate Data Warehouse following the corporate decision to migrate the primary software solution we market from a monolithic code architecture based on Oracle relational databases to a microservices architecture on Azure based on CosmosDB non-relational databases.• Designing and developing a complete Data Mart based on Oracle relational databases for the second most important corporate software solution we market.In particular, my responsibilities can be described as follows:• Designing, developing, and maintaining data integration processes from multiple primary sources (relational and non-relational) to produce consumable data sources (relational) for the Data & Analytics team, other business teams, and clients. > ODI (Oracle Data Integrator), PL/SQL, Cognos, Tableau• Designing, developing, and maintaining analyses and reports consumable by the Data & Analytics team, other business teams, and clients. > Cognos, Tableau, Excel, PL/SQL, R• Direct interaction with clients, product management and development teams, as well as other business teams to identify their data-related needs or potential collaborations, and to provide technical solutions or personalized guidance.
