Kickstart Upsells

https://apps.shopify.com/thunder-upsell-cross-sell
An app in the Shopify App Store based on Next.js, PostgresSQL, Koa, and React. I designed the UX and UI and developed the app from scratch together with my business partner.

I worked on the admin dashboard using React and the Polaris component library, including an analytics dashboard, an easy-to-use editor to customize an upsell dialog, Koa, and Next.js server.

We used a web component to display the upsell-dialog consistently across the admin dashboard and the Storefront as there is no React available there. We stuck with GraphQL wherever possible to increase performance and leveraged Shopify's webhooks where appropriate to get notified of changes on their side, such as billing, app uninstall, and GDPR requests.

Stol.it

https://stol.it
A news web app based on Laravel, MariaDB, and React. I worked mainly on the front end using React and styled-components to create custom article widgets, helped with design decisions, and migrated the application structure from consuming a legacy API to a new REST API provided by an in-house CRM.
