I am a Senior Software Engineer and Business Information Architect with dual Master's degrees in Computer Science and Economics. I have over 8 years of experience designing and implementing scalable Java backend systems, microservices, and cloud-native solutions on AWS and Databricks.
My professional philosophy, The Microeconomics of Microservices, ensures that every architectural decision—from selecting a database to defining an API—is justified by its financial efficiency (ROI). I combine hands-on software engineering with technical leadership to deliver high-performance, cost-optimized solutions that drive business value.
I specialize in establishing enterprise governance models, leading large-scale microservices transformations, and reducing operational risk across complex data systems, bridging the gap between executive business strategy and cloud technical execution.
