What I'm looking for

I'm looking to drive innovation in high-impact data, cloud, machine learning, and fraud detection work, while mentoring teams and optimizing scalable, governed, high-availability systems in agile environments.

I've built fraud detection and metadata analytics platforms at Amazon, Quantexa, and American Express, using Kafka, Spark, Snowflake, dbt, and Streamlit to process high-volume data and improve governance.

At Quantexa, I architected financial transaction pipelines reaching 1.5M events per second, reduced false positives by 20%, improved search performance by 30%, and strengthened fraud detection through entity resolution, network scoring, and contextual analytics.

Across EMBL-EBI, Samsung, Rivigo, and other data-intensive environments, I've delivered multi-omics, IoT, logistics, retail, and user analytics systems. I bring 14+ years of experience spanning Java, Scala, Python, cloud infrastructure, machine learning, data lineage, governance, and high-availability engineering.
