Demonstrated a Chrome extension that led to the organization's transition from Amplitude to BigQuery, resulting in $50K+ annual cost savings and improved data accessibility
- Built custom backend solutions to overcome platform limitations, developing a server-to-server Facebook app that enabled event-based tracking, eliminating data gaps and improving data completeness by 100%. Designed automation workflows to ensure seamless data integration, reducing manual intervention and enhancing real-time insights
- Using data to drive actionable insights and recommendations to support growth, efficiency, and day-to-day operations for political consultancy in Eastern Europe
