Who I Am
Clean system design. Fast experiences. Products built for growth.

My strength is in backend architecture, APIs, and data modeling, with a product mindset on the frontend: clarity, performance, and details that feel intentional.
I care about clean architecture and operational excellence: secure defaults, observability, maintainable code, and smooth developer experience so teams move fast without breaking trust.
