What I bring
Frontend work shaped by clarity, structured delivery and practical implementation.
My background combines interface implementation, delivery discipline and production experience across websites and campaign environments.

Design-aware engineering
I translate typography, spacing, interaction states and visual direction into frontend work that feels considered in the browser.
03
Structured delivery
I work comfortably with deadlines, revisions, content constraints and production requirements without losing implementation quality.
04
Clear communication of technical work
I can explain decisions, tradeoffs and frontend contribution clearly for teammates, clients and hiring review.
