What I bring to a product team.

Capability 1 of 4

Work beyond the interface across REST and WebSocket integrations, Node.js and Express APIs, and Java and Spring services.
Accessible delivery
Carry responsive behavior, WCAG accessibility, interaction testing, and release detail through the full implementation.
03Selected Work
Work that turns product thinking into interfaces.
A focused set of products where interface quality is backed by architecture, testing, and honest system boundaries.
