At Greenvolt Group, I deliver Business Intelligence solutions for teams across European markets, turning fragmented data into centralized dashboards. My work includes executive reporting, multi-source data integration, advanced DAX modeling, and workflow automation with Power Automate.

Earlier, at IBM, I assisted in developing a web-based solution for managing third-party power of attorney documents, using JavaScript, Vue.js, HTML, CSS, and Python.
