Architecture Leadership

17+ Years of Enterprise IT Experience

I bridge business strategy, enterprise architecture, and engineering execution to design technology solutions that are practical, scalable, secure, and aligned with organizational goals.

I work with business stakeholders, engineering teams, security architects, enterprise architects, and operations teams to move architecture from strategy to practical delivery.

My recent work includes payment gateway modernization, cloud migration governance, API-led integration, observability, and PCI DSS-aligned secure architecture across distributed enterprise platforms.
