## Story

At American Express, I worked on cardmember and marketing experiences, including credit-card comparison tools, campaign landing pages, and responsive interfaces.
I helped migrate frontend functionality from Dojo to jQuery while maintaining existing experimentation and analytics integrations. The work involved delivering interface changes within an established financial-services platform.

## Achievements

- Moved the frontend from Dojo to jQuery.
- Built credit-card marketing screens: comparison sliders and landing pages.
- Wired responsive layouts, A/B testing, and analytics.
