Message

At usePepper, I led full-stack development for e-commerce features, building React and TypeScript interfaces and Node.js services with REST APIs, authentication, and integrations. I also improved site speed and server performance through code splitting, caching, database query improvements, and API refactoring.

As a freelance Frontend Developer, I developed Shopify solutions for small businesses, including custom themes, Liquid templates, and storefront components. I integrated third-party apps and configured merchant-editable content, while building responsive interfaces with React, JavaScript, and Tailwind CSS.
