What I'm looking for

I’m looking for a senior Data Analyst role where I can lead reporting and analytics (SQL, Power BI, Python), collaborate with stakeholders in Agile, and drive cloud migration and data accuracy improvements that turn insights into business decisions.

I’m a Data Analyst with 10+ years of experience building actionable insights through SQL, Power BI, Python, and data warehousing. I gather requirements, optimize databases, create dashboards, and deliver clear reporting that drives business decisions—consistently improving data accuracy and reducing processing time. I also support large-scale cloud migrations while collaborating with cross-functional teams using Agile methodologies.

Most recently, I built and standardized 500+ commercial reports in IBM Cognos and Power BI for Ally Bank, leading stakeholder meetings and partnering with UI/UX to refine reporting requirements and deliver user-friendly dashboards. I supported cloud migration by auditing 500+ reports to document tables, fields, and schemas, and I created Jira-based management systems to reduce administrative tasks and improve visibility. Previously at NEORIS, I led data analyst efforts for an oil multinational, optimizing databases, coaching up to 11 team members, and advancing ETL migration to a Data Warehouse using Azure Data Factory (migrated from SSIS), with dashboard development in Power BI and improved tracking through Azure DevOps and Jira.
