At Western Union, I migrated a batch pipeline to real-time event processing, delivering a minimum annual saving of EUR 2.5M at no additional cost.
I designed and built a Snowflake clickstream analytics platform for Adobe Analytics event data across web and app channels. Its bronze–silver–gold architecture processes Parquet and JSON files containing 6,000+ attributes.
I also contributed to migrating 25+ data pipelines across 5+ database systems, improving storage efficiency by 30% and reducing operational costs by 40%. I built reusable Talend ETL/ELT frameworks and optimized Snowflake stored procedures to reduce execution time by 30%.
On my E-Commerce Analytics Pipeline project, I used Python and Airflow to ingest data into Snowflake, then modelled it with dbt and presented business-ready aggregations in a Streamlit dashboard. I also built an EEG seizure-detection project with real-time SMS alerts using Twilio.
