About

I work on digital products across fintech, mobile, and enterprise, from the user experience to the infrastructure that keeps them dependable in production. Architecture, cloud infrastructure and consistent delivery are what I focus on most. I use AI-assisted tools when they genuinely help, not as a substitute for good engineering.
