What I'm looking for

I'm open to full-time or contract remote engagements in backend or full-stack roles, where I can own systems end-to-end and contribute to architectural decisions.

I've built and owned production backend systems for Vita online pharmacy, «Планета здоровья», and Aptk as an outsourced developer at Platformi. I designed the Vita mobile app's brand-page builder end-to-end, with roughly 60% of its logic implemented in PostgreSQL stored functions.

My work includes improving SQL data-retrieval performance by 20% and migrating a production PostgreSQL cluster to Yandex Cloud with no data loss. I also contribute to backend and DevOps architectural decisions and maintain Docker containers across multiple servers.

Previously, I built cross-chain bridge and NFT-minting functionality at Sfxdx, integrating crypto wallets, smart contracts, Polygon, Ethereum, and BSC. At Texel, I worked across React and Node.js on a virtual clothing try-on product, including a Shopify plugin and AI Stylist Chrome extension.

I'm comfortable moving across backend, DevOps, and frontend work as projects require, and I use Claude Code daily in my production development workflow.
