Shopify developer, building one store and everything around it.
I work on a single electronics retailer on Shopify — a Dawn-based Liquid storefront — and the software that keeps it fed: a back-office app that ties the store to Ukrainian banking, marketplaces and shipping, a desktop tool that syncs supplier prices, an AI storefront assistant, and a public discounts app on the Shopify App Store.

AI, with the boring parts included
I use AI daily for scaffolding, tests and migrations, and I stay responsible for architecture, security and whether the thing is actually correct. The projects I ship with it come with an eval set, guardrails and a stated cost per request.
There's a working example on this site: an assistant grounded in these case studies that cites the section it answered from, and refuses when the answer isn't there.
Stack
Marked honestly: production means I've shipped and maintained it on a live store; working means I've built with it but wouldn't claim depth.

Who you'd be working with
I came to development from e-commerce marketing. For about two years now I've worked almost entirely on Shopify — one store's theme, and the apps and integrations behind it.
On design: I implement, I don't originate. Give me a Figma file or an existing brand and you'll get it back responsive, accessible and matching the tokens. I'm not the person to invent the visual language.
