WORK
Systems that had to hold.
Selected builds arranged like a project wall. Open any tile for the full delivery story.
RECOMMENDATIONS
What teams get.
Delivery under real constraints
Product work across remote teams, client delivery, security needs, API contracts, performance targets, and test coverage.
Interfaces that stay usable
Accessibility, keyboard navigation, responsive behavior, and fast-loading screens designed for actual user workflows.
STACK
What I run in production.
Build the interface, the system around it, and the guardrails.
The stack is less about tool collection and more about shipping frontend systems that stay fast, testable, and adaptable as the product grows.
