Financial data engineering, payment processing, accounting reconciliation, treasury, regulatory reporting — powered by AI/ML, time-series forecasting, and the lens of financial engineering.

About

Engineering at the intersection of
finance and technology.

Senior Engineering Leader specializing in building financial technology platforms — from distributed data systems and cloud-native architectures to AI/ML pipelines spanning time-series forecasting, machine learning algorithms, and LLM-enabled automation.

Deep domain expertise across the financial value chain — payment processing, transaction postings, accounting reconciliation, financial planning & reporting, treasury operations, regulatory compliance, and the interplay of the three financial statements that underpin enterprise financial integrity.

At PayPal, I lead an engineering teams geographically located operating mission-critical payment and financial data platforms at global scale. Earlier at Bank of New York Mellon, I engineered data pipelines for the NetX360 wealth management and stock trading platform at the world's largest asset management company.

Currently pursuing a Doctorate in Financial Engineering at Penn State, researching AI-driven cash-flow forecasting for large-scale payment networks. Architect and named inventor on a USPTO patent (pending) for a Treasury Cash Positioning system.
