What I'm looking for

I seek a senior frontend role building data-rich, user-focused web apps on cloud-native stacks, with collaborative teams that value accessibility, performance, and opportunities to lead frontend engineering.

I am a creative and versatile software engineer with 10+ years building interactive, data-driven web and mobile applications across energy, healthcare and SaaS domains.

I specialize in modern UI frameworks including Svelte, SvelteKit, React and Ember.js, and I build cross-platform mobile experiences with React Native and Flutter. I have led frontend architecture work—most recently for the Integrated Energy Data Resource (IEDR)—and shipped interactive mapping and data-grid solutions using Mapbox.js and AG Grid.

I collaborate closely with backend and cloud teams, working with Node.js, Express, Ruby on Rails, GraphQL and PostgreSQL, and I deploy scalable frontends on AWS and Azure. I prioritize accessibility, performance, CI/CD automation and secure RBAC integrations using Keycloak and MSAL.

I bring pragmatic leadership to frontend initiatives, a strong emphasis on user-focused interfaces and proven results improving data load performance and deployment velocity. I am motivated to join teams solving complex data problems and to drive robust, maintainable frontend systems that scale.
