Proof, not promises
Three apps. Built, shipped, and run by me.
These aren't portfolio mockups or client work I can only describe vaguely. They're live Shopify apps I built, shipped through App Store review, and still support every day. So when I build for you, I already know what review rejects, what breaks at scale, and which features merchants actually open after week one.

01 · Cart drawer & in-cart upsells
Flash Cart Drawer Upsell
A fully customizable slide-out cart drawer that lifts average order value with in-cart upsells, tiered reward bars, discounts, and trust builders. No theme code required.

Under the hood: The drawer renders inside Shadow DOM, so your theme's CSS can never break it, and it can never break your theme.

Under the hood: Files live on AWS S3 behind CloudFront signed URLs, so buyers get fast downloads and links can't be shared forever.
