I came to development from e-commerce marketing. Since 2024 I've worked almost entirely on Shopify: one store's theme and the apps and integrations behind it, plus part-time work with a Shopify agency.
Six projects, one Shopify store.
100+ orders a day
processed through it, every day
A custom Shopify app on Gadget.dev, tying the store to Ukrainian banking, fiscal receipts, a marketplace, a courier and its suppliers.
11 Admin UI extensions · 6 systems wired · ~40 data models mirrored
Shopify App Store
a public app any merchant can install
A public Shopify app that makes Google's automated discounts actually apply at checkout, as a Shopify Function.

2025 · AI / agentic
A shopper-facing chat agent on Claude and MCP — catalogue search, cart building and order status, in Ukrainian and Russian.
2024 · Integration
A desktop app that pulls prices and stock from eight suppliers, re-prices them, and bulk-updates the store and its marketplace feeds.
2023–2025 · Headless
The store's previous headless build on Hydrogen and Oxygen — retired in 2025 when it moved back to a Liquid theme.
It's one store — informatica.com.ua — but the work spreads well past the theme.
I hold a master's degree in IT, but started out in e-marketing, keeping an electronics retailer's website running on WordPress. A 12-month fullstack program and a React internship later, I moved into development properly, and in 2024 I took over the same retailer's Shopify build.
The storefront is a customised Dawn theme in Liquid, with the interactive parts written as plain Web Components rather than a framework. Around it sits a custom Shopify app on Gadget.dev for banking, fiscal receipts and the Rozetka marketplace; an Electron price-sync tool; an AI chat assistant on Claude and the Model Context Protocol; and a public Shopify app for Google's automated discounts.
Since July 2025 I also work part-time with a Shopify agency, on Checkout UI Extensions and an AI blog-generator app for merchants.
