Senior Backend Engineer & Systems Architect

From data-centric foundations to production backend architecture and platform ownership.

cat about.md

Software engineer with 4+ years across data analytics, database engineering, and backend development in banking and enterprise environments.

My engineering path started in analytics-heavy environments where SQL optimization, ETL automation, and validation workflows were mission-critical. That foundation gave me a practical perspective on data correctness and system behavior under load.

I later transitioned into backend development for banking products, contributing to payment integrations, transaction logic, insurance workflows, and production APIs used by internal and customer-facing systems.

Today I lead architecture and backend execution for contract and product work, owning system design, modular service boundaries, database performance, deployment strategy, and long-term maintainability.
