About Me

Senior Frontend Engineer with 9+ years of experience in React, Next.js, TypeScript, Vue 3, design systems, and API-connected applications.

I build scalable frontend systems and reusable component libraries for customer-facing applications and internal teams. At For Crew Only, I own technical decisions across the customer website, catalog administration, warehouse Scanner, ship-side Kiosk, and Salesforce. My work connects shopping, package tracking, warehouse operations, delivery, returns, and payments through React, Next.js, TypeScript, GraphQL, and REST APIs.

My enterprise background at Norwegian Cruise Line Holdings included Vue 3 and TypeScript modernization, multi-brand design systems, design tokens, Storybook, Chromatic, versioned npm packages, booking flows, and SVG-based deck plan interactions integrated with REST APIs.

Earlier work spans WordPress corporate sites, custom templates, ACF, Pods, PHP, CodeIgniter, dashboards, protected routes, and API-driven business functionality. Across projects, I use AI-assisted development workflows with GitHub Copilot, OpenAI Codex, and Claude Code for planning, implementation, debugging, testing, code review, and release validation.
