What I'm looking for

I'm looking to lead data, AI, and machine learning engineering initiatives that modernize cloud platforms, improve secure data movement, and deliver measurable business outcomes.

At PayPal, I lead data and machine learning engineering teams building secure, real-time data movement platforms and AI solutions for merchant onboarding, retention, and cross-sell.

I've led a team of 13 engineers, migrated thousands of legacy jobs to unified cloud platforms, and delivered machine learning models with a combined ROI of $20 million. My work includes Claude MCP-based automation, reinforcement learning experimentation, and PySpark accelerators that reduced deep-learning training time by 20%.

Previously at Tavant, I architected AWS and GCP analytics platforms for Experian, Activision, Undertone, and SEGA, supporting analytics across 300M+ consumers and modernizing large-scale data workloads with Spark, Hadoop, Hive, BigQuery, and Redshift.
