At Quanam, I design and maintain ETL processes and data warehouse models in Oracle and Oracle Warehouse Builder. I also write and optimize complex SQL queries; my query optimization improved report performance by 30%.
I develop reports and dashboards in IBM Cognos, Power BI, and Apache Superset for business teams and management. I also gather requirements from business users and provide support for report users.
I designed and developed an automated process for creating and sending daily reports with IBM Cognos and Oracle, reducing manual work by 80%.
Alongside my BI and data engineering work, I develop web applications with JavaScript, Node.js, and Python/Flask, as well as automated trading tools in Pine Script and MQL5.
