About
Since 2019 I have worked freelance, usually as the only frontend developer on the project: I pick the stack, set up the architecture and build the storefront for online shops selling into Europe and the Middle East.
Most often I move shops from Magento to Next.js and MedusaJS. On Mobelaris, pages loaded 60% faster and conversion rose 18% after the move. For shops staying on Shopify I write Liquid themes, embed React apps built with Vite, and build Shopify apps in Node.js that sync products or send quote requests to Zoho CRM.
Before that I built Progressive Web Apps with React and Redux at Feedin & Wishare, and securities processing software at FSS.
