About

A systems-minded engineer turning complex product and platform problems into dependable software.

I’m a Senior Full-Stack Engineer and Systems Architect with more than nine years of experience engineering high-throughput, data-heavy systems and intelligent automation pipelines.

My work spans multi-tenant microservices, real-time synchronization, enterprise ETL, metadata lineage, fintech, cloud migration, mobile products, and AI-enabled workflows for organizations including Walmart and teams across Australia, Europe, the United States, France, and Saudi Arabia.

I work comfortably across Java and Spring Boot, Python and FastAPI, React and Next.js, event-driven platforms, cloud infrastructure, and the delivery practices needed to move complex systems safely into production.
